When the LDAP backend is used, remote users can trigger a KDC daemon crash and denial of service.
CVE-2011-1529
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 (sid), these problems have been fixed in version 1.10+dfsg~alpha1-1.
