Amazon Linux 2023 Security Advisory: ALAS2023-2025-1154
Advisory Released Date: 2025-09-08
Advisory Updated Date: 2025-09-08
Severity:
Important
Issue Overview:
A flaw was found in libxslt where the attribute type, atype, flags are modified in a way that corrupts internal memory management. When XSLT functions, such as the key() process, result in tree fragments, this corruption prevents the proper cleanup of ID attributes. As a result, the system may access freed memory, causing crashes or enabling attackers to trigger heap corruption. (CVE-2025-7425)
Affected Packages:
libxml2
Issue Correction:
Run dnf update libxml2 --releasever 2023.8.20250908 or dnf update --advisory ALAS2023-2025-1154 --releasever 2023.8.20250908 to update your system.
More information on how to update your system can be found on this page: Amazon Linux 2023 documentation
