The remote AlmaLinux 9 host has packages installed that are affected by multiple vulnerabilities as referenced in the ALSA-2023:0383 advisory.

  • libXpm: compression commands depend on $PATH (CVE-2022-4883)

  • libXpm: Runaway loop on width of 0 and enormous height (CVE-2022-44617)

  • libXpm: Infinite loop on unclosed comments (CVE-2022-46285)

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