Oracle Linux 4 / 5 : xmlsec1 (ELSA-2009-1428)

Medium Nessus Plugin ID 67921


The remote Oracle Linux host is missing one or more security updates.


From Red Hat Security Advisory 2009:1428 :

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.

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.


Update the affected xmlsec1 packages.
