-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA512

CVE-2013-2155: Apache Santuario XML Security for C++ contains denial
of service and hash length bypass issues while processing HMAC signatures

Severity: Critical

Vendor: The Apache Software Foundation

Versions Affected: Apache Santuario XML Security for C++ library versions
prior to V1.7.1

Description: A bug exists in the processing of the output length of an
HMAC-based XML Signature that would cause a denial of service when
processing specially chosen input. Exploitation of this issue does
not require authenticated content.

In very unusual cases, inputs could be chosen in such a way that
the fix for the issue in CVE-2009-0217 could be bypassed, enabling
improper verification of a signature.

Mitigation: Applications that support HMAC signatures and are using library
versions older than V1.7.1 should upgrade as soon as possible. Distributors
of older versions should apply the patches from this subversion revision:

http://svn.apache.org/viewvc?view=revision&revision=1493960
