  - Issue summary: The POLY1305 MAC (message authentication code) implementation contains a bug that might
    corrupt the internal state of applications running on PowerPC CPU based platforms if the CPU provides
    vector instructions. Impact summary: If an attacker can influence whether the POLY1305 MAC algorithm is
    used, the application state might be corrupted with various application dependent consequences. The
    POLY1305 MAC (message authentication code) implementation in OpenSSL for PowerPC CPUs restores the
    contents of vector registers in a different order than they are saved. Thus the contents of some of these
    vector registers are corrupted when returning to the caller. The vulnerable code is used only on newer
    PowerPC processors supporting the PowerISA 2.07 instructions. The consequences of this kind of internal
    application state corruption can be various - from no consequences, if the calling application does not
    depend on the contents of non-volatile XMM registers at all, to the worst consequences, where the attacker
    could get complete control of the application process. However unless the compiler uses the vector
    registers for storing pointers, the most likely consequence, if any, would be an incorrect result of some
    application dependent calculations or a crash leading to a denial of service. The POLY1305 MAC algorithm
    is most frequently used as part of the CHACHA20-POLY1305 AEAD (authenticated encryption with associated
    data) algorithm. The most common usage of this AEAD cipher is with TLS protocol versions 1.2 and 1.3. If
    this cipher is enabled on the server a malicious client can influence whether this AEAD cipher is used.
    This implies that TLS server applications using OpenSSL can be potentially impacted. However we are
    currently not aware of any concrete application that would be affected by this issue therefore we consider
    this a Low severity security issue. (CVE-2023-6129)

Note that Nessus relies on the presence of the package as reported by the vendor.");
