"The AlmaLinux 9.2 host has packages installed that are affected by multiple vulnerabilities as referenced in the TuxCare
ALMALINUX9.2:CLSA-2024:1727979765 advisory.

  - There is a MEDIUM severity vulnerability affecting CPython. Regular expressions that allowed excessive
    backtracking during tarfile.TarFile header parsing are vulnerable to ReDoS via specifically-crafted tar
    archives. (CVE-2024-6232)

  - 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)

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