Heap out-of-bounds write in wolfSSL's DecodeObjectId() function in wolfcrypt/src/asn.c allows authenticated remote attackers to trigger memory corruption through two distinct mechanisms: insufficient bounds checking when outSz equals 1, and confusion between buffer byte size and element count across multiple callers, permitting crafted OIDs with 33+ arcs to overflow a 32-arc buffer. CVSS 2.3 reflects low impact (data modification only, no confidentiality loss), but the vulnerability affects cryptographic certificate and message parsing across all wolfSSL versions up to 5.9.0. No public exploit identified at time of analysis.

Wasmtime prior to versions 24.0.7, 36.0.7, 42.0.2, and 43.0.1 allows authenticated remote attackers to corrupt memory by providing malicious realloc return values during string transcoding between WebAssembly components, enabling writes to arbitrary memory locations up to 4GiB away from linear memory base. On default configurations with 4GiB virtual memory reservation and guard pages, exploitation typically triggers process abort via unmapped memory access; however, configurations with reduced memory reservation and disabled guard pages risk corruption of host data structures or other guest linear memories.

Wasmtime's pooling allocator leaks linear memory contents between WebAssembly instances when configured with specific non-default settings (memory_guard_size=0, memory_reservation<4GiB, max_memory_size=memory_reservation). Affected versions 28.0.0 through 36.0.6, 42.0.0-42.0.1, and 43.0.0 allow authenticated local attackers with high attack complexity to read sensitive data from previously-mapped memory due to incorrect virtual memory permission reset logic. Vendor-released patches: 36.0.7, 42.0.2, and 43.0.1. No public exploit identified at time of analysis.

Memory sandbox escape in Wasmtime's Winch compiler (versions 25.0.0 to before 36.0.7, 42.0.2, 43.0.1) enables authenticated WebAssembly guests to access arbitrary host process memory outside linear-memory boundaries. Exploitation requires non-default Winch backend activation via -Ccompiler=winch flag. Attackers can read up to 32KiB before memory start or ~4GiB after, with theoretical potential for unlimited in-process memory access due to improper 32-bit offset handling in 64-bit registers. Consequences include host process crashes (DoS), sensitive data exfiltration, or remote code execution through memory writes. Affects aarch64 (confirmed PoC) and x86-64 (theoretical). Publicly available exploit code exists.

Arbitrary memory read/write vulnerability in Bytecode Alliance Wasmtime versions 32.0.0 through 36.0.6, 42.0.0-42.0.1, and 43.0.0 allows authenticated remote attackers to escape WebAssembly sandbox restrictions. The Cranelift compilation backend on aarch64 architecture miscompiles specific heap access patterns, creating divergent address computations where bounds checks validate one address while loads access another, enabling sandbox escape through unrestricted host memory access. Exploitation requires 64-bit WebAssembly linear memories with Spectre mitigations and signals-based-traps disabled. No public exploit identified at time of analysis.

Wasmtime runtime versions prior to 24.0.7, 36.0.7, 42.0.2, and 43.0.1 incorrectly validate UTF-16 string byte lengths during component-model encoding transcoding, causing out-of-bounds memory reads that trigger process termination via segfault in default configurations or potentially expose host memory when guard pages are disabled. Authenticated users with UI interaction can trigger this denial-of-service vulnerability; reading beyond linear memory requires non-standard Wasmtime configuration without guard pages. No public exploit code has been identified at time of analysis.

Out-of-bounds read in osslsigncode versions 2.12 and earlier allows local attackers to crash the application via crafted PE files with malicious section headers during page-hash computation. The vulnerability exists in the pe_page_hash_calc() function, which fails to validate that section headers' PointerToRawData and SizeOfRawData values reference valid file regions. An attacker can trigger the flaw by providing a malicious PE file for signing with page hashing enabled (-ph flag) or by providing an already-signed malicious PE file for verification, where verification does not require the -ph flag. CVSS 5.5 with high availability impact; no public exploit identified at time of analysis.

Osslsigncode 2.12 and earlier contains an integer underflow in PE page-hash computation that allows local attackers to trigger an out-of-bounds heap read and crash the process via a specially crafted PE file with SizeOfHeaders larger than SectionAlignment.

Issue summary: Converting an excessively large OCTET STRING value to a hexadecimal string leads to a heap buffer overflow on 32 bit platforms. Impact summary: A heap buffer overflow may lead to a crash or possibly an attacker controlled code execution or other undefined behavior. If an attacker can supply a crafted X.509 certificate with an excessively large OCTET STRING value in extensions such as the Subject Key Identifier (SKID) or Authority Key Identifier (AKID) which are being converted to hex, the size of the buffer needed for the result is calculated as multiplication of the input length by 3. On 32 bit platforms, this multiplication may overflow resulting in the allocation of a smaller buffer and a heap buffer overflow. Applications and services that print or log contents of untrusted X.509 certificates are vulnerable to this issue. As the certificates would have to have sizes of over 1 Gigabyte, printing or logging such certificates is a fairly unlikely operation and only 32 bit platforms are affected, this issue was assigned Low severity. The FIPS modules in 3.6, 3.5, 3.4, 3.3 and 3.0 are not affected by this issue, as the affected code is outside the OpenSSL FIPS module boundary.

Out-of-bounds read in OpenSSL 3.6.0-3.6.1 allows denial of service when AES-CFB128 encryption or decryption processes partial cipher blocks on x86-64 systems with AVX-512 and VAES support. Vulnerability triggers when input buffer ends at a memory page boundary with subsequent unmapped page, causing crashes. Exploitation requires unauthenticated network access but demands specific architectural conditions (AVX-512/VAES) and partial block handling. No public exploit identified at time of analysis. EPSS percentile 5% indicates low observed exploitation activity.
