This module provides interfaces for parsing and manipulating XML files and allows Perl programmers to use the highly capable validating XML parser and the high performance DOM implementation. Security Fix(es): 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) An update for perl-XML-LibXML is now available for openEuler-20.03-LTS-SP4,openEuler-22.03-LTS-SP4,openEuler-24.03-LTS-SP1,openEuler-24.03-LTS-SP3,openEuler-24.03-LTS-SP4. openEuler Security has rated this update as having a security impact of high.
