From Red Hat Security Advisory 2008:0836 :
Updated libxml2 packages that fix a security issue are now available.
This update has been rated as having moderate security impact by the Red Hat Security Response Team.
[Updated 26th August 2008] The original fix used in this errata caused some applications using the libxml2 library in an unexpected way to crash when used with updated libxml2 packages. We have updated the packages for Red Hat Enterprise Linux 3, 4 and 5 to use a different fix that does not break affected applications.
The libxml2 packages provide a library that allows you to manipulate XML files. It includes support to read, modify, and write XML and HTML files.
A denial of service flaw was found in the way libxml2 processes certain content. If an application linked against libxml2 processes malformed XML content, it could cause the application to stop responding. (CVE-2008-3281)
Red Hat would like to thank Andreas Solberg for responsibly disclosing this issue.
All users of libxml2 are advised to upgrade to these updated packages, which contain a backported patch to resolve this issue.
