This roll up patch serves as a cumulative upgrade for Red Hat JBoss BRMS
5.3.1. It includes various bug fixes. The following security issue is also
fixed with this release:

A flaw was found in the way Apache Santuario XML Security for Java
validated XML signatures. Santuario allowed a signature to specify an
arbitrary canonicalization algorithm, which would be applied to the
SignedInfo XML fragment. A remote attacker could exploit this to spoof an
XML signature via a specially-crafted XML signature block. (CVE-2013-2172)
