Debian DSA-143-1 : krb5 - integer overflow

critical Nessus Plugin ID 14980

Synopsis

The remote Debian host is missing a security-related update.

Description

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.

Solution

Upgrade the kerberos packages immediately.

This problem has been fixed in version 1.2.4-5woody1 for the current stable distribution (woody) and in version 1.2.5-2 for the unstable distribution (sid). Debian 2.2 (potato) is not affected since it doesn't contain krb5 packages.
