CERT's vulnerabilities, advisories and incident notes: CA-2002-29, VU#875073.
More information:

Tom Yu and Sam Hartman of MIT discovered another stack 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.

This problem has been fixed in version 1.2.4-5woody3 for the current stable distribution (woody) and in version 1.2.6-2 for the unstable distribution (sid). The old stable distribution (potato) is not affected since no krb5 packages are included.

We recommend that you upgrade your krb5 packages immediately.

Fixed in:

Debian GNU/Linux 3.0 (woody)
