Red Hat Security Advisory: libcupsfilters security update
Two security vulnerabilities were identified in libcupsfilters, a library used by the CUPS printing system and related filters. The first vulnerability (CVE-2026-64611) involves CPU exhaustion caused by an infinite loop in the cfIEEE1284NormalizeMakeModel() function. The second vulnerability (CVE-2026-64612) allows a CUPS image filter process to abort when processing a malformed PNG file. These issues could impact printing services on affected Red Hat Enterprise Linux 10 systems. Red Hat has issued a security update to address these vulnerabilities.
AI Analysis
Technical Summary
The libcupsfilters library, which provides common functions for the cups-browsed daemon and printing filters in CUPS, contains two vulnerabilities. CVE-2026-64611 is a CPU exhaustion vulnerability caused by an infinite loop in the cfIEEE1284NormalizeMakeModel() function. CVE-2026-64612 causes the CUPS image filter process to abort when handling malformed PNG files. Both vulnerabilities affect the libcupsfilters component used in Red Hat Enterprise Linux 10. Red Hat has released an update to fix these issues as detailed in advisory RHSA-2026:56965.
Potential Impact
The CPU exhaustion vulnerability (CVE-2026-64611) could allow an attacker to cause denial of service by triggering an infinite loop, consuming excessive CPU resources. The malformed PNG vulnerability (CVE-2026-64612) could cause the CUPS image filter process to abort, potentially disrupting printing operations. Both vulnerabilities have a moderate security impact and do not indicate remote code execution or privilege escalation based on the provided data.
Mitigation Recommendations
Red Hat has released an official security update for libcupsfilters in Red Hat Enterprise Linux 10 to address these vulnerabilities. Users should apply the update as described in Red Hat advisory RHSA-2026:56965 and the referenced article https://access.redhat.com/articles/11258. No additional mitigation steps are indicated by the vendor advisory.
