USN-474-1: xscreensaver vulnerability
12 June 2007
It was discovered that xscreensaver did not correctly validate the
return values from network authentication systems such as LDAP or NIS.
A local attacker could bypass a locked screen if they were able to
interrupt network connectivity.
The problem can be corrected by updating your system to the following package versions:
- xscreensaver - 4.24-5ubuntu2.1
- xscreensaver - 4.24-4ubuntu2.1
- xscreensaver - 4.23-4ubuntu8.1
After a standard system upgrade you need to restart your session to
effect the necessary changes.
