CWE ID 787


CVE-2023-6129 is a vulnerability affecting multiple products, including OpenSSL for PowerPC CPUs. The vulnerability lies in the implementation of the POLY1305 MAC algorithm, which may corrupt the internal state of applications if the CPU provides vector instructions. If an attacker can influence the use of the POLY1305 MAC algorithm, it can lead to application state corruption with various consequences. This vulnerability specifically affects newer PowerPC processors that support PowerISA 2.07 instructions. The potential danger to organizations depends on the application's reliance on non-volatile XMM registers, ranging from no consequences to more severe impacts. Remediation for this vulnerability involves updating to a patched version of OpenSSL that addresses the issue. The CVSS score for this vulnerability is 6.5, indicating a medium severity level with high attack complexity and potential impact on availability.
