Amazon Linux 2023 Security Advisory: ALAS2023-2026-1795
Advisory Released Date: 2026-06-08
Advisory Updated Date: 2026-06-08
Severity:
Medium
Issue Overview:
XML::LibXML versions through 2.0210 for Perl read out-of-bounds heap memory when parsing XML node names containing truncated UTF-8 byte sequences.
A node name ending in the middle of a multi byte UTF-8 sequence causes the parser to read past the end of the input string into adjacent heap memory.
Any Perl process that passes attacker controlled strings to XML::LibXML's DOM node-name methods can reach this path on the default API. The likely consequence is a crash, causing denial of service. (CVE-2026-8177)
Affected Packages:
perl-XML-LibXML
Issue Correction:
Run dnf update perl-XML-LibXML --releasever 2023.12.20260608 or dnf update --advisory ALAS2023-2026-1795 --releasever 2023.12.20260608 to update your system.
