   Manager Daemon          
   Previously Published As: 103175

   Product
Sun Ray Server Software 3.1
Sun Ray Server Software 3.1.1

Sun Ray Server Software 2.0

   Bug ID: 6571384

   Date of Workaround Release: 18-Dec-2007

   Date of Resolved Release: 24-Sep-2008

   SA Document Body
Security vulnerabilities in the Sun Ray Device Manager daemon (utdevmgrd(1M)):

   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) without patch
       114880-12
     * Sun Ray Server Software 3.0 (for Solaris 8, 9) without patch
       118979-03
     * 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 3.0 without patch 119836-03
     * 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. 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 2.0 (for Solaris 8 and 9) with patch
       114880-12 or later
     * Sun Ray Server Software 3.0 (for Solaris 8, 9) with patch
       118979-03 or later
     * 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 3.0 with patch 119836-03 or later
     * Sun Ray Server Software 3.1 with patch 120881-07 or later
