(RHSA-2006:0498) xscreensaver security update

XScreenSaver is a collection of screensavers.

A keyboard focus flaw was found in the way XScreenSaver prompts the user to
enter their password to unlock the screen. XScreenSaver did not properly
ensure it had proper keyboard focus, which could leak a users password to
the program with keyboard focus. This behavior is not common, as only certain
applications exhibit this focus error. (CVE-2004-2655)

Several flaws were found in the way various XScreenSaver screensavers
create temporary files. It may be possible for a local attacker to create a
temporary file in way that could overwrite a different file to which the user
running XScreenSaver has write permissions. (CVE-2003-1294)

Users of XScreenSaver should upgrade to this updated package, which
contains backported patches to correct these issues.
