Ubuntu Security Notice USN-843-1           October 06, 2009
backuppc vulnerability

A security issue affects the following Ubuntu releases:

Ubuntu 8.04 LTS
Ubuntu 8.10
Ubuntu 9.04

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 8.04 LTS:
  backuppc                        3.0.0-4ubuntu1.1

Ubuntu 8.10:
  backuppc                        3.1.0-3ubuntu2.1

Ubuntu 9.04:
  backuppc                        3.1.0-4ubuntu1.1

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

Details follow:

It was discovered that BackupPC did not restrict normal users from setting
the ClientNameAlias parameter. An authenticated user could exploit this to
gain access to unauthorized hosts. This update fixed the issue by
preventing normal users from modifying the ClientNameAlias configuration
