Description Vincent Danen 2011-01-18 12:05:08 EST
Changes in the KDC network code in the krb5-1.9 release introduced a bug that allows a null pointer dereference, which would cause the KDC to crash.  Any request packet that is sufficiently malformed that the KDC would not generate a response packet can trigger this bug.

This flaw will be addressed as part of MITKRB5-SA-2011-002.  It does not affect any version of Kerberos prior to 1.9.
Comment 2 Vincent Danen 2011-02-08 16:26:27 EST
This issue is now public:



This issue did not affect the versions of krb5 as shipped with Red Hat Enterprise Linux 3, 4, 5 or 6.
