Posted on: 11/05/2008 07:25 PM

A new system-tools-backends regression update is available for Ubuntu Linux. Here the announcement:

Ubuntu Security Notice USN-663-1 November 05, 2008
system-tools-backends regression

A security issue affects the following Ubuntu releases:

Ubuntu 8.10

This advisory also applies to the corresponding versions of
Kubuntu, Edubuntu, and Xubuntu.

The problem can be corrected by upgrading your system to the
following package versions:

Ubuntu 8.10:
system-tools-backends 2.6.0-1ubuntu1.1

In general, a standard system upgrade is sufficient to effect the
necessary changes.

Details follow:

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.
