The remote AlmaLinux 8 host has a package installed that is affected by multiple vulnerabilities as referenced in the ALSA-2024:4267 advisory.
* fontforge: command injection via crafted filenames (CVE-2024-25081)
* fontforge: command injection via crafted archives or compressed files (CVE-2024-25082)
Tenable has extracted the preceding description block directly from the AlmaLinux security advisory.
Note that Nessus has not tested for these issues but has instead relied only on the application’s self-reported version number.
