"The CentOS Linux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the
TuxCare CENTOS-STREAM8:CLSA-2026:1772810768 advisory.

  - There is a LOW severity vulnerability affecting CPython, specifically the 'http.cookies' standard library
    module. When parsing cookies that contained backslashes for quoted characters in the cookie value, the
    parser would use an algorithm with quadratic complexity, resulting in excess CPU resources being used
    while parsing the value. (CVE-2024-7592)

  - The poplib module, when passed a user-controlled command, can have additional commands injected using
    newlines. Mitigation rejects commands containing control characters. (CVE-2025-15367)

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