USN-663-1: system-tools-backends regression
5 November 2008
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 8.10
It was discovered that passwords changed (or new users created) via the “Users and Groups” tool were created with 3DES hashing. This reduced the security of stored user passwords, and was a regression from the correct MD5 hashing. This update fixes the problem; future password changes will correct the hashing used. We apologize for the inconvenience.
The problem can be corrected by updating your system to the following package versions:
To update your system, please follow these instructions: https://wiki.ubuntu.com/Security/Upgrades.
In general, a standard system upgrade is sufficient to effect the necessary changes.
