Debian DSA-2031-1 : krb5 - use-after-free

Medium Nessus Plugin ID 45479

Synopsis

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

Description

Sol Jerome discovered that kadmind service in krb5, a system for authenticating users and services on a network, allows remote authenticated users to cause a denial of service (daemon crash) via a request from a kadmin client that sends an invalid API version number.

Solution

Upgrade the krb5 package.

For the stable distribution (lenny), this problem has been fixed in version 1.6.dfsg.4~beta1-5lenny3.
