=========================================================== 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.
