Synopsis :

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

Description :

Updated libxml2 packages that fix various security issues are now
available for Red Hat Enterprise Linux 2.1.

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

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)

A denial of service flaw was found in the way libxml2 processed
certain content. If an application linked against libxml2 processed
malformed XML content, it could cause the application to use an
excessive amount of CPU time and memory, and stop responding.
(CVE-2003-1564)

All users of libxml2 are advised to upgrade to these updated packages,
which contain backported patches to resolve these issues.
