It was discovered that the Key Distribution Center (KDC) in Kerberos 5
crashes when processing certain crafted requests:

CVE-2011-1528
        When the LDAP backend is used, remote users can trigger
        a KDC daemon crash and denial of service.

        When the LDAP or Berkeley DB backend is used, remote users
        can trigger a NULL pointer dereference in the KDC daemon
        and a denial of service.
        
The oldstable distribution (lenny) is not affected by these problems.

For the stable distribution (squeeze), these problems have been fixed
in version 1.8.3+dfsg-4squeeze5.

For the testing distribution (wheezy) and the unstable distribution
