"An integer overflow bug has been discovered in the RPC library used by
the Kerberos 5 administration system, which is derived from the SunRPC
library. This bug could be exploited to gain unauthorized root access
to a KDC host. It is believed that the attacker needs to be able to
authenticate to the kadmin daemon for this attack to be successful. No
exploits are known to exist yet."

distribution (sid). Debian 2.2 (potato) is not affected since it
doesn't contain krb5 packages."
