Ubuntu Security Notice USN-58-1
10th January, 2005
krb5 vulnerability
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 4.10
Details
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.
Update instructions
The problem can be corrected by updating your system to the following package version:
- Ubuntu 4.10:
- libkadm55
- krb5-admin-server
- libkrb53
- krb5-kdc
To update your system, please follow these instructions: https://wiki.ubuntu.com/Security/Upgrades.
