Ubuntu Security Notice USN-663-1          November 05, 2008
system-tools-backends regression
https://launchpad.net/bugs/287134
===========================================================

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.
