The following issues have been fixed:

- CVE-2011-1528: In releases krb5-1.8 and later, the KDC
can crash due to an assertion failure.
- CVE-2011-1529: In releases krb5-1.8 and later, the KDC
can crash due to a null pointer dereference.

Both bugs could be triggered by unauthenticated remote
attackers. Additionally CVE-2011-1526 was fixed that
allowed authenticated users to access files via krb5 ftpd
they should not have access to.
