Tom Yu and Sam Hartman of MIT discovered another stack-based buffer overflow in the kadm_ser_wrap_in function in the Kerberos v4 administration server. This kadmind bug has a working exploit code circulating, hence it is considered serious. The MIT krb5 implementation includes support for version 4, including a complete v4 library, server side support for krb4, and limited client support for v4.
