"The AlmaLinux 9.2 host has packages installed that are affected by a vulnerability as referenced in the TuxCare
ALMALINUX9.2:CLSA-2026:1785421184 advisory.

  - Downloading and building modules with malicious version strings can cause local code execution. On systems
    with Mercurial (hg) installed, downloading modules from non-standard sources (e.g., custom domains) can
    cause unexpected code execution due to how external VCS commands are constructed. This issue can also be
    triggered by providing a malicious version string to the toolchain. On systems with Git installed,
    downloading and building modules with malicious version strings can allow an attacker to write to
    arbitrary files on the filesystem. This can only be triggered by explicitly providing the malicious
    version strings to the toolchain and does not affect usage of @latest or bare module paths.
    (CVE-2025-68119)

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