Ubuntu 4.10 : krb5 vulnerability (USN-58-1)

high Nessus Plugin ID 20676

Synopsis

The remote Ubuntu host is missing one or more security-related patches.

Description

Michael Tautschnig discovered a possible buffer overflow in the add_to_history() function in the MIT Kerberos 5 implementation.
Performing a password change did not properly track the password policy's history count and the maximum number of keys. This could cause an array overflow and may have allowed authenticated users (not necessarily one with administrative privileges) to execute arbitrary code on the KDC host, compromising an entire Kerberos realm.

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Update the affected packages.
