RedHat: RHSA-2010-3025-02 Important: libxml2 Security Vulnerability

red hat
Calendar Grey November 30, 2009
Dist Redhat Esm H88
Recent updates to xerces-j2 packages mitigate notable security vulnerabilities on Red Hat platforms. Ensure you upgrade promptly to boost your application’s security.
Updated xerces-j2 packages that fix a security issue are now available for Red Hat Enterprise Linux 5

Solution

Before applying this update, make sure that all previously-released errata relevant to your system have been applied.

This update is available via Red Hat Network. Details on how to use the Red Hat Network to apply this update are available at

Summary

The xerces-j2 packages provide the Apache Xerces2 Java Parser, a high-performance XML parser. A Document Type Definition (DTD) defines the legal syntax (and also which elements can be used) for certain types of files, such as XML files.
A flaw was found in the way the Apache Xerces2 Java Parser processed the SYSTEM identifier in DTDs. A remote attacker could provide a specially-crafted XML file, which once parsed by an application using the Apache Xerces2 Java Parser, would lead to a denial of service (application hang due to excessive CPU use). (CVE-2009-2625)
Users should upgrade to these updated packages, which contain a backported patch to correct this issue. Applications using the Apache Xerces2 Java Parser must be restarted for this update to take effect.
