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.
The problem can be corrected by updating your system to the following
Ubuntu 12.04 LTS:
Ubuntu 10.04 LTS:
