=====================================================================

1. Summary:

Updated xmlsec1 packages that fix one security issue are now available for
Red Hat Enterprise Linux 4 and 5.

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

2. Relevant releases/architectures:

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 XML Security Library is a C library based on libxml2 and OpenSSL. It
implements the XML Signature Syntax and Processing and XML Encryption
Syntax and Processing standards. HMAC is used for message authentication
using cryptographic hash functions. The HMAC algorithm allows the hash
output to be truncated (as documented in RFC 2104).

A missing check for the recommended minimum length of the truncated form of
HMAC-based XML signatures was found in xmlsec1. An attacker could use this
flaw to create a specially-crafted XML file that forges an XML signature,
allowing the attacker to bypass authentication that is based on the XML
Signature specification. (CVE-2009-0217)

Users of xmlsec1 should upgrade to these updated packages, which contain
a backported patch to correct this issue. After installing the updated
packages, applications that use the XML Security Library must be restarted
for the update to take effect.

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/docs/DOC-11259

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

511915 - CVE-2009-0217 xmlsec1, mono, xml-security-c, xml-security-1.3.0-1jpp.ep1.*: XMLDsig HMAC-based signatures spoofing and authentication bypass
