There are packages installed that are affected by a vulnerability referenced in the following CVE:

  - When passing data to the b64decode(), standard_b64decode(), and urlsafe_b64decode() functions in the
    "base64" module the characters "+/" will always be accepted, regardless of the value of "altchars"
    parameter, typically used to establish an "alternative base64 alphabet" such as the URL safe alphabet.
    This behavior matches what is recommended in earlier base64 RFCs, but newer RFCs now recommend either
    dropping characters outside the specified base64 alphabet or raising an error. The old behavior has the
    possibility of causing data integrity issues. This behavior can only be insecure if your application uses
    an alternate base64 alphabet (without "+/"). If your application does not use the "altchars" parameter or
    the urlsafe_b64decode() function, then your application does not use an alternative base64 alphabet. The
    attached patches DOES NOT make the base64-decode behavior raise an error, as this would be a change in
    behavior and break existing programs. Instead, the patch deprecates the behavior which will be replaced
    with the newly recommended behavior in a future version of Python. Users are recommended to mitigate by
    verifying user-controlled inputs match the base64 alphabet they are expecting or verify that their
    application would not be affected if the b64decode() functions accepted "+" or "/" outside of altchars.
    (CVE-2025-12781)

The AlmaLinux 9.2 host has packages installed that are affected by multiple vulnerabilities as referenced in the TuxCare ALMALINUX9.2:CLSA-2026:1773136115 advisory.

  - When loading a plist file, the plistlib module reads data in size specified by the file itself, meaning a     malicious file can cause OOM and DoS issues (CVE-2025-13837)

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

The remote SUSE Linux SLED15 / SLED_SAP15 / SLES15 / SLES_SAP15 / openSUSE 15 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2026:0767-1 advisory.

    - CVE-2025-11468: header injection when folding a long comment in an email header containing exclusively     unfoldable       characters (bsc#1257029).
    - CVE-2025-12781: inadequate parameter check can cause data integrity issues (bsc#1257108).
    - CVE-2025-15282: user-controlled data URLs parsed may allow injecting headers (bsc#1257046).
    - CVE-2025-15366: user-controlled command can allow additional commands injected using newlines     (bsc#1257044).
    - CVE-2025-15367: control characters may allow the injection of additional commands (bsc#1257041).
    - CVE-2026-0672: HTTP header injection via user-controlled cookie values and parameters when using     http.cookies.Morsel       (bsc#1257031).
    - CVE-2026-0865: user-controlled header containing newlines can allow injecting HTTP headers     (bsc#1257042).
