Also known as Orpheus' Lyre, this vulnerability could be used by an attacker to mount a service impersonation attack on the client if he's on the network path between the client and the service.
More details can be found on the vulnerability website ([link moved to references]).
For Debian 7 Wheezy, these problems have been fixed in version 1.6~git20120403+dfsg1-2+deb7u1.
We recommend that you upgrade your heimdal packages.
