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
