===================================================================== CERT-Renater Note d'Information No. 2007/VULN535 _____________________________________________________________________ DATE : 20/12/2007 HARDWARE PLATFORM(S) : / OPERATING SYSTEM(S) : Systems running Sun Ray Device Manager daemon. ====================================================================== Sun(sm) Alert Notification * Sun Alert ID: 103175 * Synopsis: Security Vulnerabilities in the Sun Ray Device Manager Daemon * Category: Security * Product: Sun Ray Server Software 3.1, Sun Ray Server Software 3.1.1, Sun Ray Server Software 3.0, Sun Ray Server Software 2.0 * BugIDs: 6571384 * Avoidance: Patch, Workaround * State: Workaround * Date Released: 18-Dec-2007 * Date Closed: * Date Modified: 1. Impact Security vulnerabilities in the Sun Ray Device Manager daemon (utdevmgrd(1M)) may allow a local or remote unprivileged user to create or delete arbitrary directories on the server, or cause the Device Manager daemon to crash resulting in an interruption of peripheral device service to Sun Ray users. Sun acknowledges with thanks, Danny Quist and Anthony Clark at Los Alamos National Labs for bringing these issues to our attention. 2. Contributing Factors These issues can occur in the following releases: SPARC Platform * Sun Ray Server Software 2.0 (for Solaris 8, 9) * Sun Ray Server Software 3.0 (for Solaris 8, 9) * Sun Ray Server Software 3.1 (for Solaris 8, 9, and 10) without patch 120879-07 x86 Platform * Sun Ray Server Software 3.1 (for Solaris 10) without patch 120880-07 Linux * Sun Ray Server Software 3.1 without patch 120881-07 * Sun Ray Server Software 3.1.1 without patch 124388-02 Note 1: Sun Ray Server Software 4.0 is not affected by these issues. Note 2: Sun Ray Server Software 2.0 and 3.0 are not supported on Solaris 10. Note 3: Sun Ray Server Software 3.0 is not supported on the Solaris x86 platform. (3.1 only) Note 4: Sun Ray Server Software 3.1 is not supported on Solaris 8 or Solaris 9 on the x86 platform. (Solaris 10 only) To determine the version of the Sun Ray Server Software on a Solaris system, the following command can be run: # /usr/bin/pkgparam VERSION SUNWuto 3.1_32,REV=2005.08.24.08.55 To determine the version of Sun Ray Server Software on a Linux system, the following command can be run: # /bin/rpm -q SUNWuto SUNWuto-3.1-32.21 3. Symptoms If the Sun Ray server has been affected by the directory-related vulnerabilities, directories may be found at unexpected locations in the filesystem, or directories may be discovered to be missing from the filesystem. If the Sun Ray server has been affected by the crash vulnerability, the "utdevmgrd" process will terminate and will produce a core file in "/var/opt/SUNWut/log" or in the location determined by coreadm(1M). 4. Relief/Workaround To work around these issues, the Sun Ray Device Manager daemon may be made non-executable and existing instances of the daemon may be stopped. To apply this workaround, execute the following commands: # /bin/chmod ogw-x /opt/SUNWut/lib/utdevmgrd # /usr/bin/pkill -STOP utdevmgrd # /usr/bin/pkill -TERM utdevmgrd # /opt/SUNWut/sbin/utrestart Note: Applying the above workaround will result in the disabling of application access to smartcards, access to USB peripherals, and access to serial devices. Mouse, keyboard and audio access will be unaffected. To undo the workaround, execute the following commands: # /bin/chmod ogw+x /opt/SUNWut/lib/utdevmgrd # /opt/SUNWut/sbin/utrestart Executing "utrestart" will interrupt Sun Ray sessions running on this server, but the sessions will continue and may be resumed after the restart has completed. 5. Resolution These issues are addressed in the following releases: SPARC Platform * Sun Ray Server Software 3.1 (for Solaris 8, 9, and 10) with patch 120879-07 or later x86 Platform * Sun Ray Server Software 3.1 (for Solaris 10) with patch 120880-07 or later Linux Platform * Sun Ray Server Software 3.1 without patch 120881-07 or later * Sun Ray Server Software 3.1.1 without patch 124388-02 or later This Sun Alert notification is being provided to you on an "AS IS" basis.
