Original advisory text
Important: perl-XML-Parser security update
This module provides ways to parse XML documents. It is built on top of XML::Parser::Expat, which is a lower level interface to James Clark's expat library. Each call to one of the parsing methods creates a new instance of XML::Parser::Expat which is then used to parse the document. Expat options may be provided when the XML::Parser object is created. These options are then passed on to the Expat object on each parse call. They can also be given as extra arguments to the parse methods, in which case they override options given at XML::Parser creation time.
Security Fix(es):
* perl-xml-parser: XML::Parser: Memory corruption via deeply nested XML files (CVE-2006-10003)
* perl-xml-parser: XML::Parser for Perl: Heap corruption and denial of service from crafted XML input (CVE-2006-10002)
