MIT krb5 Security Advisory 2010-006 - When the MIT krb5 KDC receives certain Kerberos TGS request messages, it may dereference an uninitialized pointer while processing authorization data, causing a crash, or in rare cases, unauthorized information disclosure, ticket modification, or execution of arbitrary code. The crash may be triggered by legitimate requests. This is an implementation vulnerability in MIT krb5, and not a vulnerability in the Kerberos protocol.
