Background
perl-XML-Parser is a Perl module that provides methods for parsing XML documents. It is built on the XML::Parser::Expat interface, which utilizes James Clark's expat library. The module allows users to create XML::Parser objects with customizable options for parsing XML files. However, it has been found to be vulnerable to memory corruption issues when handling deeply nested XML files, which can lead to severe security risks.
