Title:CentOS Update for xmlsec1 CESA-2009:1428 centos5 i386
Summary:The remote host is missing an update for the 'xmlsec1'; package(s) announced via the referenced advisory.
The remote host is missing an update for the 'xmlsec1'
package(s) announced via the referenced advisory.

Vulnerability Insight:
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.

Affected Software/OS:
xmlsec1 on CentOS 5

Please install the updated packages.
