Description

Apache Santuario implements the XML Signature Syntax and Processing and XML
Encryption Syntax and Processing standards.

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)

Web Platform installation (including all applications and configuration
