"The remote CentOS Linux 9 host has packages installed that are affected by multiple vulnerabilities as referenced in the
python3.11-3.11.5-1.el9 build changelog.

  - An issue was discovered in Python before 3.8.18, 3.9.x before 3.9.18, 3.10.x before 3.10.13, and 3.11.x
    before 3.11.5. It primarily affects servers (such as HTTP servers) that use TLS client authentication. If
    a TLS server-side socket is created, receives data into the socket buffer, and then is closed quickly,
    there is a brief window where the SSLSocket instance will detect the socket as not connected and won't
    initiate a handshake, but buffered data will still be readable from the socket buffer. This data will not
    be authenticated if the server-side TLS peer is expecting client certificate authentication, and is
    indistinguishable from valid TLS stream data. Data is limited in size to the amount that will fit in the
    buffer. (The TLS connection cannot directly be used for data exfiltration because the vulnerable code path
    requires that the connection be closed on initialization of the SSLSocket.) (CVE-2023-40217)

  - An issue was discovered in Python 3.11 through 3.11.4. If a path containing '\0' bytes is passed to
    os.path.normpath(), the path will be truncated unexpectedly at the first '\0' byte. There are plausible
    cases in which an application would have rejected a filename for security reasons in Python 3.10.x or
    earlier, but that filename is no longer rejected in Python 3.11.x. (CVE-2023-41105)

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