Description

A denial of service vulnerability was found in the Shibboleth (an federated identity framework) Service Provider. When processing certain malformed SAML message generated by an authenticated attacker, the daemon could crash.

For the Debian 6 'Squeeze' distribution, this problem has been fixed in version 2.3.1+dfsg-5+deb6u1.

We recommend that you upgrade your shibboleth-sp2 packages.

NOTE: Tenable Network Security has extracted the preceding description block directly from the DLA security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
