Detail

Problem Description:

Updated libxml2 packages that fix a security issue are now available for Red Hat Enterprise Linux 3, 4, and 5.

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

2. Relevant releases/architectures:

Red Hat Enterprise Linux AS version 3 - i386, ia64, ppc, s390, s390x, x86_64 Red Hat Desktop version 3 - i386, x86_64 Red Hat Enterprise Linux ES version 3 - i386, ia64, x86_64 Red Hat Enterprise Linux WS version 3 - i386, ia64, x86_64 Red Hat Enterprise Linux AS version 4 - i386, ia64, ppc, s390, s390x, x86_64 Red Hat Enterprise Linux Desktop version 4 - i386, x86_64 Red Hat Enterprise Linux ES version 4 - i386, ia64, x86_64 Red Hat Enterprise Linux WS version 4 - i386, ia64, x86_64 Red Hat Enterprise Linux Desktop (v. 5 client) - i386, x86_64 RHEL Desktop Workstation (v. 5 client) - i386, x86_64 Red Hat Enterprise Linux (v. 5 server) - i386, ia64, ppc, s390x, x86_64

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/):

Title: USN-815-1 -- libxml2 vulnerabilities
Description: It was discovered that libxml2 did not correctly handle root XML document element DTD definitions. If a user were tricked into processing a specially crafted XML document, a remote attacker could cause the application linked against libxml2 to crash, leading to a denial of service. It was discovered that libxml2 did not correctly parse Notation and Enumeration attribute types. If a user were tricked into processing a specially crafted XML document, a remote attacker could cause the application linked against libxml2 to crash, leading to a denial of service. USN-644-1 fixed a vulnerability in libxml2. This advisory provides the corresponding update for Ubuntu 9.04. Original advisory details: It was discovered that libxml2 did not correctly handle long entity names.
