The remote AlmaLinux 9 host has packages installed that are affected by multiple vulnerabilities as referenced in the ALSA-2024:7346 advisory.
* cups-browsed: cups-browsed binds on UDP INADDR_ANY:631 trusting any packet from any source ()
* cups-filters: libcupsfilters: `cfGetPrinterAttributes` API does not perform sanitization on returned IPP attributes (CVE-2024-47076)
* cups: libppd: remote command injection via attacker controlled data in PPD file ()
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.
