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.\r\n\r\nSecurity Fix(es):\n\nXML::LibXML versions through 2.0210 for Perl read out-of-bounds heap memory when parsing XML node names containing truncated UTF-8 byte sequences.\n\nA 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.\n\nAny Perl process that passes attacker controlled strings to XML::LibXML's DOM node-name methods can reach this path on the default API.
