"The version of Tencent Linux installed on the remote TencentOS Server 4 host is prior to tested version. It is,
therefore, affected by multiple vulnerabilities as referenced in the TSSA-2024:0713 advisory.

    Package updates are available for TencentOS Server 4 that fix the following vulnerabilities:

    CVE-2024-0397:
    A defect was discovered in the Python ssl module where there is a memory
    race condition with the ssl.SSLContext methods cert_store_stats() and
    get_ca_certs(). The race condition can be triggered if the methods are
    called at the same time as certificates are loaded into the SSLContext,
    such as during the TLS handshake with a certificate directory configured.
    This issue is fixed in CPython 3.10.14, 3.11.9, 3.12.3, and 3.13.0a5.

    CVE-2024-4032:
    The ipaddress module contained incorrect information about whether certain IPv4 and IPv6 addresses
    were designated as globally reachable or private. This affected the is_private and is_global
    properties of the ipaddress.IPv4Address, ipaddress.IPv4Network, ipaddress.IPv6Address, and
    ipaddress.IPv6Network classes, where values wouldnt be returned in accordance with the latest
    information from the IANA Special-Purpose Address Registries.

    CPython 3.12.4 and 3.13.0a6 contain updated information from these registries and thus have the intended
    behavior.

Tenable has extracted the preceding description block directly from the Tencent Linux security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version
number.");
