Details

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
parameter.

Update instructions

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

Ubuntu 9.04

• backuppc - 3.1.0-4ubuntu1.1

Ubuntu 8.10

• backuppc - 3.1.0-3ubuntu2.1

necessary changes.
