DESCRIPTION:
Some vulnerabilities have been reported in Apache XML Security, which
can be exploited by malicious people to cause a DoS (Denial of
Service) in an application using the library.

The vulnerabilities are caused due to off-by-one errors when creating
or verifying XML signatures of files signed with RSA, DSA, or ECDSA
keys and can be exploited to cause crashes via overly long keys.

The vulnerabilities are reported in versions prior to 1.6.1.

SOLUTION:
Update to version 1.6.1.

PROVIDED AND/OR DISCOVERED BY:
Reported in a bug report by Paulo Zanoni.
