RHSA-2009:1625 - Moderate: expat security update

Synopsis

Moderate: expat security update

Type/Severity

Security Advisory Moderate

Topic

Updated expat packages that fix two security issues are now available for Red Hat Enterprise Linux 3, 4, and 5.

This update has been rated as having moderate security impact by the Red Hat Security Response Team.

Description

Expat is a C library written by James Clark for parsing XML documents.

Two buffer over-read flaws were found in the way Expat handled malformed UTF-8 sequences when processing XML files. A specially-crafted XML file could cause applications using Expat to crash while parsing the file. (CVE-2009-3560, CVE-2009-3720)

All expat users should upgrade to these updated packages, which contain backported patches to correct these issues. After installing the updated packages, applications using the Expat library must be restarted for the update to take effect.

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 This content is not included.http://kbase.redhat.com/faq/docs/DOC-11259
