A heap-based buffer overflow vulnerability exists in the glib library's g_escape_uri_string() function due to an integer overflow in buffer size calculation when processing strings with a very large number of characters requiring URI escaping. This vulnerability affects multiple Red Hat Enterprise Linux 9.0 and 10.0 distributions across various architectures (x86_64, ARM64, IBM Z, Power). A proof-of-concept exploit is publicly available, though EPSS scoring indicates only 0.01% exploitation probability (1st percentile), suggesting limited active exploitation in the wild despite the availability of exploit code.
A flaw was found in polkit. When processing an XML policy with 32 or more nested elements in depth, an out-of-bounds write can be triggered. This issue can lead to a crash or other unexpected behavior, and arbitrary code execution is not discarded. To exploit this flaw, a high-privilege account is needed as it's required to place the malicious policy file properly.
A heap-buffer-overflow (off-by-one) flaw was found in the GnuTLS software in the template parsing logic within the certtool utility. When it reads certain settings from a template file, it allows an attacker to cause an out-of-bounds (OOB) NULL pointer write, resulting in memory corruption and a denial-of-service (DoS) that could potentially crash the system.
A heap-buffer-overread vulnerability was found in GnuTLS in how it handles the Certificate Transparency (CT) Signed Certificate Timestamp (SCT) extension during X.509 certificate parsing. This flaw allows a malicious user to create a certificate containing a malformed SCT extension (OID 1.3.6.1.4.1.11129.2.4.2) that contains sensitive data. This issue leads to the exposure of confidential information when GnuTLS verifies certificates from certain websites when the certificate (SCT) is not checked correctly.
A security vulnerability in A flaw (CVSS 6.5). Remediation should follow standard vulnerability management procedures.
A security vulnerability in libssh (CVSS 5.0). Remediation should follow standard vulnerability management procedures.
CVE-2025-5318 is an out-of-bounds read vulnerability in libssh versions before 0.11.2 caused by an incorrect comparison check in the sftp_handle function that allows authenticated remote attackers to access memory beyond the valid handle list and retrieve invalid pointers for further processing. This vulnerability enables exposure of sensitive information or denial of service, with a CVSS score of 8.1 indicating high severity. The vulnerability requires authentication and network access but has high confidentiality and availability impact.
A vulnerability has been identified in the libarchive library. This flaw can lead to a heap buffer over-read due to the size of a filter block potentially exceeding the Lempel-Ziv-Storer-Schieber (LZSS) window. This means the library may attempt to read beyond the allocated memory buffer, which can result in unpredictable program behavior, crashes (denial of service), or the disclosure of sensitive information from adjacent memory regions.
CVE-2025-5914 is an integer overflow vulnerability in libarchive's archive_read_format_rar_seek_data() function that leads to a double-free memory corruption condition. This affects all users of libarchive who process untrusted RAR archive files, potentially allowing arbitrary code execution or denial-of-service with user interaction (opening a malicious RAR file). While no KEV listing or confirmed public exploits are currently documented, the high CVSS score (7.8) and memory safety nature of the vulnerability indicate significant real-world risk if weaponized.
