RHSA-2026:8608 - Security Advisory

Topic

An update for perl-XML-Parser is now available for Red Hat Enterprise Linux 8.4 Advanced Mission Critical Update Support and Red Hat Enterprise Linux 8.4 Extended Update Support Long-Life Add-On.

Red Hat Product Security has rated this update as having a security impact of Important. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section.

Description

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)
