Amazon Linux 2023 Security Advisory: ALAS-2023-411
Advisory Release Date: 2023-10-30 23:44 Pacific
Advisory Updated Date: 2023-11-03 22:38 Pacific
Severity:
Important
Issue Overview:
libxml2 through 2.11.5 has a use-after-free that can only occur after a certain memory allocation fails. This occurs in xmlUnlinkNode in tree.c. NOTE: the vendor's position is "I don't think these issues are critical enough to warrant a CVE ID ... because an attacker typically can't control when memory allocations fail." (CVE-2023-45322)
Affected Packages:
libxml2
Issue Correction:
Run dnf update libxml2 --releasever 2023.2.20231030 to update your system.
