Amazon Linux 2023 Security Advisory: ALAS2023-2026-2127
Advisory Released Date: 2026-09-14
Advisory Updated Date: 2026-09-14
Severity:
Medium
Issue Overview:
A flaw was found in libcupsfilters and cups-filters. The PNG image reading function creates a libpng reader without installing an error recovery handler, causing the CUPS image filter process to abort when processing a malformed PNG file. An unauthenticated attacker could exploit this by submitting a specially crafted PNG print job, leading to denial of service of the in-flight print job. (CVE-2026-64612)
Affected Packages:
cups-filters
Issue Correction:
Run dnf update cups-filters --releasever 2023.12.20260914 or dnf update --advisory ALAS2023-2026-2127 --releasever 2023.12.20260914 to update your system.
