Affected: AlmaLinux:10: perl-XML-LibXML

This module implements a Perl interface to the GNOME libxml2 library which provides interfaces for parsing and manipulating XML files. This module allows Perl programmers to make use of the highly capable validating XML parser and the high performance DOM implementation.

Security Fix(es):

* perl-XML-LibXML: XML::LibXML: Denial of Service via truncated UTF-8 in XML node names (CVE-2026-8177)

For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.

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.

This module is Perl Binding for libxml2, which implements a Perl interface to the GNOME libxml2 library. 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.
