RedHat: Important: libxml2 security update Print E-mail
User Rating:      How can I rate this item?
Posted by Benjamin D. Thomas   
RedHat Linux Updated libxml2 packages that fix a security issue are now available for Red Hat Enterprise Linux 3, 4, and 5. A heap-based buffer overflow flaw was found in the way libxml2 handled long XML entity names. If an application linked against libxml2 processed untrusted malformed XML content, it could cause the application to crash or, possibly, execute arbitrary code. (CVE-2008-3529) This update has been rated as having important security impact by the Red Hat Security Response Team.

3. Description:

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 heap-based buffer overflow flaw was found in the way libxml2 handled long
XML entity names. If an application linked against libxml2 processed
untrusted malformed XML content, it could cause the application to crash
or, possibly, execute arbitrary code. (CVE-2008-3529)

All users of libxml2 are advised to upgrade to these updated packages,
which contain a backported patch to resolve this issue.

4. 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
http://kbase.redhat.com/faq/FAQ_58_10188

5. Bugs fixed (http://bugzilla.redhat.com/):

461015 - CVE-2008-3529 libxml2: long entity name heap buffer overflow
