Description

The remote host is missing updates announced in advisory RHSA-2009:1428.

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.
