Summary

cups security update

Details

CUPS is the standards-based, open source printing system developed by Apple Inc. for UNIX®-like operating systems. CUPS uses the Internet Printing Protocol (IPP) to support printing to local and network printers..

Security Fix(es):

The cupsUTF32ToUTF8() function in CUPS's cups/transcode.c lacks a source-length bound and can read past the end of the source buffer, resulting in a heap out-of-bounds read. This is reachable via SNMP supply-description parsing in backend/snmp-supplies.c with attacker-controlled content.(CVE-2026-87875)

Two case-insensitive comparisons on request-derived usernames outside the main authorization path in CUPS's scheduler (printer ACL validation and private-attribute filtering) could allow bypass of username-based access controls in certain configurations.(CVE-2026-87876)
