Heap-based buffer overflow in HDF5 (The HDF Group) before 2.2.0 lets an attacker who supplies a crafted HDF5 file corrupt heap memory in any application linked against the library, causing a crash and potentially achieving arbitrary code execution. The flaw lives in H5VM_array_fill() (src/H5VM.c) and is triggered when a dataset's unallocated/unwritten chunks are read: H5D__fill_init() derives the fill-value buffer from datatype and dataspace metadata stored in the file, and when that metadata is inconsistent with the buffer's allocated size the write overruns the buffer with attacker-controlled fill-value bytes. Exploitation is not network-reachable - it requires a victim to open or automatically process the malicious file (AV:L, UI:P per CVSS 4.0; UI:R in the 3.1 assessment), so risk is highest in data-ingest, HPC and ML pipelines that parse untrusted HDF5 inputs without an interactive user; no public exploit code has been identified at time of analysis and there is no KEV listing, though the CVSS 4.0 base score of 8.5 reflects high confidentiality, integrity and availability impact.
NULL pointer dereference in HDF5's H5Pget_fill_value function (all versions before 2.1.1) enables denial of service by processing a specially crafted HDF5 dataset file. The flaw arises when a fill value message (format version 1 or 2) carries the 'defined' flag alongside a negative size field - a malformed state the library fails to normalize to its internal 'undefined' sentinel - allowing a NULL datatype pointer to reach H5T_path_find and crash the process. No public exploit identified at time of analysis; the CVSS 4.0 score of 8.2 reflects high availability impact, but the local file-parsing vector and user interaction requirement meaningfully constrain real-world exposure.
Heap use-after-free in HDF5 h5dump utility allows local attackers to achieve arbitrary code execution when processing malicious HDF5 files. Affects HDF5 versions 1.14.1-2 and earlier from HDFGroup. Attacker must convince user to open crafted file (user interaction required, CVSS UI:R). Unauthenticated attack vector enables high-impact compromise of confidentiality, integrity, and availability. No public exploit identified at time of analysis. Vulnerability stems from premature deallocation in H5D__typeinfo_term followed by unsafe reference in H5T__conv_struct memmove operation.
Heap buffer overflow in HDF5 versions prior to 1.14.4-2 allows attackers to trigger denial-of-service or potentially achieve code execution by crafting malicious h5 files. The vulnerability affects any system parsing untrusted HDF5 data files and has public exploit code available. A patch is not yet available, leaving affected deployments at risk.
Heap-based buffer over-read in the HDF5 library's scale-offset filter decoder (H5Z__filter_scaleoffset) allows a local, unauthenticated attacker to cause a denial of service by supplying a crafted HDF5 file that a victim opens. The flaw occurs when the filter's stored minimum-bits parameter equals the datatype's full precision and the decoder attempts to copy d_nelmts * size bytes from a compressed chunk that is too short, triggering an out-of-bounds read and application crash. The vendor CVSS 4.0 vector (6.8 Medium) rates this as an availability-only impact with no confidentiality or integrity effect; no public exploit code has been identified, and the fix is available as an upstream pull request but not yet confirmed in a tagged release.
Heap use-after-free in the HDF5 library (The HDF Group, all versions before 2.3.0) is triggered when an application such as h5dump reads a dataset whose compound datatype contains floating-point members, allowing a crafted .h5 file to crash the parsing process and, depending on heap layout and allocator behaviour, potentially corrupt memory further. Exploitation requires the victim to open a malicious file locally (local vector, mandatory user interaction, no authentication needed), so it is not remotely reachable on its own. No public exploit code has been identified at time of analysis and the issue is not in CISA KEV; the vendor's own CVSS 4.0 base of 4.6 aligns with the independent assessment that the reliably demonstrated impact is a crash rather than proven code execution.
Integer underflow in HDF5 through 2.3.0 allows denial of service when processing Fletcher32-filtered datasets with chunk sizes smaller than 4 bytes. The `H5Z__filter_fletcher32` function in `H5Zfletcher32.c` subtracts the 4-byte checksum length from the input buffer size using an unsigned `size_t` without first verifying the buffer meets the minimum size, causing the result to wrap near `SIZE_MAX` and triggering a massively out-of-bounds read inside `H5_checksum_fletcher32`. Any application or pipeline calling `H5Dread` on a crafted HDF5 file - including the standard `h5ls` and `h5dump` utilities - can be crashed; no public exploit code has been identified and this vulnerability is not in CISA KEV.
Out-of-bounds heap read in HDF5's N-Bit filter decompression affects all versions through 2.3.0, allowing an attacker who can deliver a crafted HDF5 file to a user or automated pipeline to trigger application crashes and, in constrained cases, leak adjacent heap memory contents into decompressed dataset values. The three affected functions - H5Z__nbit_decompress_one_byte, H5Z__nbit_decompress_one_nooptype, and H5Z__nbit_decompress_one_atomic - advance a buffer read index without bounding it against the actual compressed chunk size, exploitable whenever H5Dread is invoked, including via common tools like h5ls and h5repack. No public exploit code has been identified at time of analysis, and this vulnerability is not listed in the CISA KEV catalog.
Null pointer dereference in HDF5 through 2.3.0 allows denial of service when a user opens a crafted file containing a malformed N-Bit filter pipeline message with zero client-data values. The function H5Z__filter_nbit unconditionally reads cd_values[0] through cd_values[4] before checking whether the array is non-NULL or contains at least 5 elements, crashing any application - including the bundled h5ls and h5repack tools - that calls H5Dread on such a dataset. No active exploitation has been confirmed (not listed in CISA KEV) and no EPSS score was available, but the fix diff publicly exposes the exact crash path, lowering the barrier for proof-of-concept development.
HDF5 library through version 2.3.0 crashes with a divide-by-zero when a process opens a crafted file containing mismatched chunk-layout and dataspace dimensionality. The missing rank validation in H5O__layout_decode allows the corrupt metadata to propagate unchecked to H5S__hyper_iter_get_seq_list, where the invalid value causes integer division by zero and application termination. Tools that automatically consume externally-supplied HDF5 files - such as the bundled h5repack utility - are the primary exposure surface; no public exploit code or confirmed active exploitation has been identified at time of analysis.
Untrusted pointer dereference in HDF5's h5dump utility (before version 2.1.1) causes a denial of service when processing specially crafted HDF5 files containing variable-length string datasets with more than one element rendered in binary mode. The stride calculation for per-element offsets becomes corrupted, causing subsequent elements to be read from misaligned memory addresses and dereferenced as pointers, crashing the tool. No public exploit code exists at time of analysis, and no active exploitation has been confirmed - the local attack vector and DoS-only impact make this a low operational priority for most environments.
Denial of service in HDF5 caused by a NULL pointer dereference when processing a crafted HDF5 file with an invalid variable-length datatype attribute. The vulnerability affects all versions of HDF5 and can be triggered by a user opening a malicious file, leading to application crash. Publicly available exploit code exists per CVSS metric.
Double free in HDF5 library allows a local attacker to cause a denial of service via a crafted file with an oversized chunk size. Processing the file with h5repack triggers an application abort, with no confidentiality or integrity impact. No active exploitation or public exploit code has been confirmed.
Heap-based buffer overflow in HDF5 through 2.1.1 enables attackers to crash applications and potentially corrupt data by providing a crafted HDF5 file. The flaw lies in the shared‑message list‑index deserializer (SOHM), allowing out‑of‑bounds heap reads and writes when a num_messages field exceeds the declared list_max. No active exploitation has been reported, but the issue is publicly documented and a proof‑of‑concept may exist in the linked issue.
Buffer underflow in HDF5 library versions through 1.14.6 corrupts memory when H5Iget_name is called with a size parameter of zero on a group identifier, writing a null terminator before the intended buffer boundary and potentially crashing the host application. Applications that ingest attacker-supplied HDF5 files and expose user-controlled size values to H5Iget_name face availability disruption and, under specific heap layouts, possible disclosure of adjacent memory contents. No public exploit has been identified at time of analysis and the vulnerability is absent from CISA KEV; the CVSS 4.0 score of 5.9 reflects the high attack complexity and required active user interaction that meaningfully constrain real-world exploitation.
Out-of-bounds read in HDF5 (all versions prior to 2.0.0) is triggered when parsing a maliciously crafted file whose array datatype metadata violates the internal invariant that element_size × nelem must equal the stored full datatype size. When a victim opens such a file, the HDF5 parser reads beyond its intended buffer boundary, causing application crash or potential memory disclosure. No active exploitation is confirmed in CISA KEV, but SSVC intelligence confirms a POC exists, and the vendor has released a patch in version 2.0.0.
Heap buffer overflow in HDF5 library versions 1.14.1-2 and earlier allows local attackers to trigger a write-based overflow in the H5T__ref_mem_setnull method by crafting malicious HDF5 files, leading to denial-of-service and potential remote code execution depending on heap exploitation complexity. Attack requires local file access and user interaction to parse a malicious file. No public exploit code identified at time of analysis.
Heap-based buffer overflow in HDF5 1.14.6 allows local attackers with low privileges to cause application crashes or potential arbitrary code execution.

Stack-based buffer overflow in HDF5 1.14.6 allows local attackers with low privileges to cause denial of service by triggering a crash in the H5G__node_cmp3 function. A public exploit is available, but exploitation requires local access, limiting widespread impact.

Local denial-of-service via resource consumption in HDF5 1.14.6 allows a low-privileged attacker to cause application unresponsiveness by exploiting a flaw in the H5C__load_entry metadata cache function. Public exploit code exists, but no active exploitation has been confirmed by CISA KEV, and EPSS indicates a very low exploitation probability (0.05%).

Heap-based buffer overflow in HDF5 (The HDF Group) before 2.2.0 lets an attacker who supplies a crafted HDF5 file corrupt heap memory in any application linked against the library, causing a crash and potentially achieving arbitrary code execution. The flaw lives in H5VM_array_fill() (src/H5VM.c) and is triggered when a dataset's unallocated/unwritten chunks are read: H5D__fill_init() derives the fill-value buffer from datatype and dataspace metadata stored in the file, and when that metadata is inconsistent with the buffer's allocated size the write overruns the buffer with attacker-controlled fill-value bytes. Exploitation is not network-reachable - it requires a victim to open or automatically process the malicious file (AV:L, UI:P per CVSS 4.0; UI:R in the 3.1 assessment), so risk is highest in data-ingest, HPC and ML pipelines that parse untrusted HDF5 inputs without an interactive user; no public exploit code has been identified at time of analysis and there is no KEV listing, though the CVSS 4.0 base score of 8.5 reflects high confidentiality, integrity and availability impact.
NULL pointer dereference in HDF5's H5Pget_fill_value function (all versions before 2.1.1) enables denial of service by processing a specially crafted HDF5 dataset file. The flaw arises when a fill value message (format version 1 or 2) carries the 'defined' flag alongside a negative size field - a malformed state the library fails to normalize to its internal 'undefined' sentinel - allowing a NULL datatype pointer to reach H5T_path_find and crash the process. No public exploit identified at time of analysis; the CVSS 4.0 score of 8.2 reflects high availability impact, but the local file-parsing vector and user interaction requirement meaningfully constrain real-world exposure.
Heap use-after-free in HDF5 h5dump utility allows local attackers to achieve arbitrary code execution when processing malicious HDF5 files. Affects HDF5 versions 1.14.1-2 and earlier from HDFGroup. Attacker must convince user to open crafted file (user interaction required, CVSS UI:R). Unauthenticated attack vector enables high-impact compromise of confidentiality, integrity, and availability. No public exploit identified at time of analysis. Vulnerability stems from premature deallocation in H5D__typeinfo_term followed by unsafe reference in H5T__conv_struct memmove operation.
Heap buffer overflow in HDF5 versions prior to 1.14.4-2 allows attackers to trigger denial-of-service or potentially achieve code execution by crafting malicious h5 files. The vulnerability affects any system parsing untrusted HDF5 data files and has public exploit code available. A patch is not yet available, leaving affected deployments at risk.
Heap-based buffer over-read in the HDF5 library's scale-offset filter decoder (H5Z__filter_scaleoffset) allows a local, unauthenticated attacker to cause a denial of service by supplying a crafted HDF5 file that a victim opens. The flaw occurs when the filter's stored minimum-bits parameter equals the datatype's full precision and the decoder attempts to copy d_nelmts * size bytes from a compressed chunk that is too short, triggering an out-of-bounds read and application crash. The vendor CVSS 4.0 vector (6.8 Medium) rates this as an availability-only impact with no confidentiality or integrity effect; no public exploit code has been identified, and the fix is available as an upstream pull request but not yet confirmed in a tagged release.
Heap use-after-free in the HDF5 library (The HDF Group, all versions before 2.3.0) is triggered when an application such as h5dump reads a dataset whose compound datatype contains floating-point members, allowing a crafted .h5 file to crash the parsing process and, depending on heap layout and allocator behaviour, potentially corrupt memory further. Exploitation requires the victim to open a malicious file locally (local vector, mandatory user interaction, no authentication needed), so it is not remotely reachable on its own. No public exploit code has been identified at time of analysis and the issue is not in CISA KEV; the vendor's own CVSS 4.0 base of 4.6 aligns with the independent assessment that the reliably demonstrated impact is a crash rather than proven code execution.
Integer underflow in HDF5 through 2.3.0 allows denial of service when processing Fletcher32-filtered datasets with chunk sizes smaller than 4 bytes. The `H5Z__filter_fletcher32` function in `H5Zfletcher32.c` subtracts the 4-byte checksum length from the input buffer size using an unsigned `size_t` without first verifying the buffer meets the minimum size, causing the result to wrap near `SIZE_MAX` and triggering a massively out-of-bounds read inside `H5_checksum_fletcher32`. Any application or pipeline calling `H5Dread` on a crafted HDF5 file - including the standard `h5ls` and `h5dump` utilities - can be crashed; no public exploit code has been identified and this vulnerability is not in CISA KEV.
Out-of-bounds heap read in HDF5's N-Bit filter decompression affects all versions through 2.3.0, allowing an attacker who can deliver a crafted HDF5 file to a user or automated pipeline to trigger application crashes and, in constrained cases, leak adjacent heap memory contents into decompressed dataset values. The three affected functions - H5Z__nbit_decompress_one_byte, H5Z__nbit_decompress_one_nooptype, and H5Z__nbit_decompress_one_atomic - advance a buffer read index without bounding it against the actual compressed chunk size, exploitable whenever H5Dread is invoked, including via common tools like h5ls and h5repack. No public exploit code has been identified at time of analysis, and this vulnerability is not listed in the CISA KEV catalog.
Null pointer dereference in HDF5 through 2.3.0 allows denial of service when a user opens a crafted file containing a malformed N-Bit filter pipeline message with zero client-data values. The function H5Z__filter_nbit unconditionally reads cd_values[0] through cd_values[4] before checking whether the array is non-NULL or contains at least 5 elements, crashing any application - including the bundled h5ls and h5repack tools - that calls H5Dread on such a dataset. No active exploitation has been confirmed (not listed in CISA KEV) and no EPSS score was available, but the fix diff publicly exposes the exact crash path, lowering the barrier for proof-of-concept development.
HDF5 library through version 2.3.0 crashes with a divide-by-zero when a process opens a crafted file containing mismatched chunk-layout and dataspace dimensionality. The missing rank validation in H5O__layout_decode allows the corrupt metadata to propagate unchecked to H5S__hyper_iter_get_seq_list, where the invalid value causes integer division by zero and application termination. Tools that automatically consume externally-supplied HDF5 files - such as the bundled h5repack utility - are the primary exposure surface; no public exploit code or confirmed active exploitation has been identified at time of analysis.
Untrusted pointer dereference in HDF5's h5dump utility (before version 2.1.1) causes a denial of service when processing specially crafted HDF5 files containing variable-length string datasets with more than one element rendered in binary mode. The stride calculation for per-element offsets becomes corrupted, causing subsequent elements to be read from misaligned memory addresses and dereferenced as pointers, crashing the tool. No public exploit code exists at time of analysis, and no active exploitation has been confirmed - the local attack vector and DoS-only impact make this a low operational priority for most environments.
Denial of service in HDF5 caused by a NULL pointer dereference when processing a crafted HDF5 file with an invalid variable-length datatype attribute. The vulnerability affects all versions of HDF5 and can be triggered by a user opening a malicious file, leading to application crash. Publicly available exploit code exists per CVSS metric.
Double free in HDF5 library allows a local attacker to cause a denial of service via a crafted file with an oversized chunk size. Processing the file with h5repack triggers an application abort, with no confidentiality or integrity impact. No active exploitation or public exploit code has been confirmed.
Heap-based buffer overflow in HDF5 through 2.1.1 enables attackers to crash applications and potentially corrupt data by providing a crafted HDF5 file. The flaw lies in the shared‑message list‑index deserializer (SOHM), allowing out‑of‑bounds heap reads and writes when a num_messages field exceeds the declared list_max. No active exploitation has been reported, but the issue is publicly documented and a proof‑of‑concept may exist in the linked issue.
Buffer underflow in HDF5 library versions through 1.14.6 corrupts memory when H5Iget_name is called with a size parameter of zero on a group identifier, writing a null terminator before the intended buffer boundary and potentially crashing the host application. Applications that ingest attacker-supplied HDF5 files and expose user-controlled size values to H5Iget_name face availability disruption and, under specific heap layouts, possible disclosure of adjacent memory contents. No public exploit has been identified at time of analysis and the vulnerability is absent from CISA KEV; the CVSS 4.0 score of 5.9 reflects the high attack complexity and required active user interaction that meaningfully constrain real-world exploitation.
Out-of-bounds read in HDF5 (all versions prior to 2.0.0) is triggered when parsing a maliciously crafted file whose array datatype metadata violates the internal invariant that element_size × nelem must equal the stored full datatype size. When a victim opens such a file, the HDF5 parser reads beyond its intended buffer boundary, causing application crash or potential memory disclosure. No active exploitation is confirmed in CISA KEV, but SSVC intelligence confirms a POC exists, and the vendor has released a patch in version 2.0.0.
Heap buffer overflow in HDF5 library versions 1.14.1-2 and earlier allows local attackers to trigger a write-based overflow in the H5T__ref_mem_setnull method by crafting malicious HDF5 files, leading to denial-of-service and potential remote code execution depending on heap exploitation complexity. Attack requires local file access and user interaction to parse a malicious file. No public exploit code identified at time of analysis.
