[USN-1444-1] BackupPC vulnerability


Ubuntu Security Notice USN-1444-1
May 17, 2012

backuppc vulnerability

A security issue affects these releases of Ubuntu and its derivatives:

  • Ubuntu 12.04 LTS
  • Ubuntu 11.10
  • Ubuntu 11.04
  • Ubuntu 10.04 LTS
  • Ubuntu 8.04 LTS


BackupPC could be made to expose sensitive information over the network.

Software Description:

  • backuppc: high-performance, enterprise-grade system for backing up PCs


It was discovered that BackupPC did not properly sanitize its input when
processing RestoreFile error messages, resulting in a cross-site
scripting (XSS) vulnerability. With cross-site scripting vulnerabilities,
if a user were tricked into viewing server output during a crafted server
request, a remote attacker could exploit this to modify the contents, or
steal confidential data, within the same domain.

Update instructions:

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

Ubuntu 12.04 LTS:
backuppc 3.2.1-2ubuntu1.1

Ubuntu 11.10:
backuppc 3.2.1-1ubuntu1.2

Ubuntu 11.04:
backuppc 3.2.0-3ubuntu4.3

Ubuntu 10.04 LTS:
backuppc 3.1.0-9ubuntu1.3

Ubuntu 8.04 LTS:
backuppc 3.0.0-4ubuntu1.4

In general, a standard system update will make all the necessary changes.
