Detail
| Problem Description: An updated xscreensaver package that fixes two security flaws is now available for Red Hat Enterprise Linux 2.1 and 3. This update has been rated as having moderate security impact by the Red Hat Security Response Team. 2. Relevant releases/architectures: Red Hat Enterprise Linux AS (Advanced Server) version 2.1 - i386, ia64 Red Hat Linux Advanced Workstation 2.1 - ia64 Red Hat Enterprise Linux ES version 2.1 - i386 Red Hat Enterprise Linux WS version 2.1 - i386 Red Hat Enterprise Linux AS version 3 - i386, ia64, ppc, s390, s390x, x86_64 Red Hat Desktop version 3 - i386, x86_64 Red Hat Enterprise Linux ES version 3 - i386, ia64, x86_64 Red Hat Enterprise Linux WS version 3 - i386, ia64, x86_64 3. Problem description: 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. 4. Solution: Before applying this update, make sure all previously released errata relevant to your system have been applied. This update is available via Red Hat Network. To use Red Hat Network, launch the Red Hat Update Agent with the following command: up2date This will start an interactive process that will result in the appropriate RPMs being upgraded on your system. 5. Bug IDs fixed (http://bugzilla.redhat.com/): 182287 - CVE-2003-1294 xscreensaver temporary file flaws 188149 - CVE-2004-2655 xscreensaver passes password to other applications |
