Important: cups-filters security update

Details

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.

CVE-2024-47076 (GCVE-0-2024-47076)

Vulnerability from cvelistv5 – Published: 2024-09-26 21:18 – Updated: 2025-11-03 22:19

Title

libcupsfilters's cfGetPrinterAttributes5 does not validate IPP attributes returned from an IPP server

Summary

CUPS is a standards-based, open-source printing system, and `libcupsfilters` contains the code of the filters of the former `cups-filters` package as library functions to be used for the data format conversion tasks needed in Printer Applications. The `cfGetPrinterAttributes5` function in `libcupsfilters` does not sanitize IPP attributes returned from an IPP server. When these IPP attributes are used, for instance, to generate a PPD file, this can lead to attacker controlled data to be provided to the rest of the CUPS system.

Severity

8.6 (High)
