Description

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.
