RHEL 3 / 4 / 5 : expat (RHSA-2009:1625)

Medium Nessus Plugin ID 43046


The remote Red Hat host is missing one or more security updates.


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.

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.


Update the affected expat and / or expat-devel packages.
