CVE-2025-61915
Description
A flaw was found in cups. A user in group defined by SystemGroup directive in /etc/cups/cups-files.conf can use the cups web ui to change the config and insert a malicious line. Then the cupsd process which runs as root will parse the new config and cause an out-of-bound write.
Statement
The highest threat of this flaw is to system availability. A local attacker with high privileges, specifically a user belonging to the SystemGroup as defined in /etc/cups/cups-files.conf, could exploit the CUPS web interface to introduce a malicious configuration line into cupsd.conf, leading to a denial of service.
Mitigation
Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base or stability.
Common Vulnerability Scoring System (CVSS) Score Details
Info alert:Important note
CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).
