TITLE:
OpenSAML KeyDescriptor "use" Security Bypass

SECUNIA ADVISORY ID:
SA36868

VERIFY ADVISORY:
http://secunia.com/advisories/36868/

DESCRIPTION:
A security issue has been reported in OpenSAML, which can be
exploited by malicious people to bypass certain security features.

The security issue is caused due to the library ignoring the "use"
tag of the "KeyDescriptor" element, which can be exploited to e.g.
use the certificate for both signing and encryption, although the
metadata specifies only one of the cases.

The security issue is reported in versions prior to 2.2.1.

SOLUTION:
Update to version 2.2.1.

PROVIDED AND/OR DISCOVERED BY:
Reported by the vendor.

ORIGINAL ADVISORY:
https://bugs.internet2.edu/jira/browse/CPPOST-28
