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
