CVE-2007-5585 low priority: Ubuntu including 1 source packages (xscreensaver), 9 status rows across 9 suites (dapper, edgy, feisty, gutsy, hardy, intrepid, jaunty, karmic, upstream): ignored 4, not-affected 4, released 1.
xscreensaver 5.03 and earlier, when running without xscreensaver-gl-extras (GL extras) installed, crashes when /usr/bin/xscreensaver-gl-helper does not exist and a user attempts to unlock the screen, which allows attackers with physical access to gain access to the locked session.
