Summary
Package updates are available for Amazon Linux 2 that fix the following vulnerabilities: CVE-2026-64612: 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.
