The remote Redhat Enterprise Linux 9 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2024:7346 advisory.
The cups-filters package contains back ends, filters, and other software that was once part of the core Common UNIX Printing System (CUPS) distribution but is now maintained independently.
Security Fix(es):
* 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 ()
For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.
Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.
Note that Nessus has not tested for these issues but has instead relied only on the application’s self-reported version number.
