Sun(sm) Alert Notification

     * Sun Alert ID: 57653
     * Synopsis: libXpm Security Vulnerabilities Affect the Motif Library
       (libXm)
     * Category: Security
     * Product: Solaris Common Desktop Environment (CDE), Sun Java
       Desktop System (JDS)
     * BugIDs: 5086486, 6175145
     * Avoidance: Patch, Workaround
     * State: Committed
     * Date Released: 08-Oct-2004
     * Date Closed:
     * Date Modified:

1. Impact

   Several security vulnerabilities have been reported in the X Pixmap
   (libXpm) library which also affect the Motif library (libXm) shipped
   with Solaris and JDS for Linux since libXm includes the affected
   libXpm routines. These security vulnerabilities may allow a remote
   unprivileged user to execute arbitrary code with the privileges of a
   local user if that user loads an X Pixmap (.xpm) format image file
   from an untrusted source with an application that is linked with the
   Motif library (libXm).

   Note: The Motif library (libXm) can be used to manipulate and display
   small images in Motif applications.

   This issue is also described in the following documents:

2. Contributing Factors

   This issue can occur in the following releases:

   SPARC Platform

     * Solaris 7
     * Solaris 8
     * Solaris 9

   x86 Platform

     * Solaris 7
     * Solaris 8
     * Solaris 9

   Linux Platform

     * Sun Java Desktop System (JDS) 2003 without the updated RPMs
       (patch-9400)
     * Sun Java Desktop System (JDS) Release 2 without the updated RPMs
       (patch-9400)

   Notes:

    1. JDS for Solaris is not impacted by this issue.
    2. This issue only occurs with Open Motif versions
       openmotif-2.2.2-502 or earlier.

   To determine if a Solaris application is linked with the libXm
   library, the ldd(1) can be utilized. For example:

    $ ldd /usr/dt/bin/uil | grep libXm.so 
    libXm.so.4 =>    /usr/dt/lib/libXm.so.4

   To determine if a Linux application is linked with the libXm library,
   the ldd(1) utility can be utilized. For example:

    $ ldd /usr/X11R6/bin/uil | grep libXm
    libXm.so.3 => /usr/X11R6/lib/libXm.so.3 (0x40033000)


   To determine the release of JDS for Linux installed on a system, the
   following command can be run:

    % cat /etc/sun-release
    Sun Java Desktop System, Release 2 -build 10b (GA)
    Assembled 30 March 2004

   To determine the version of Open Motif, the following command can be
   run:

    % rpm -qf /usr/X11R6/lib/libXm.so.3
    openmotif-2.2.2-522

3. Symptoms

   There are no predictable symptoms that would indicate the described
   issue has been exploited.

   Solution Summary [5]Top

4. Relief/Workaround

   To work around the described issue, do not load X PixMap (.xmp) images
   from untrusted sources.

5. Resolution

   This issue is resolved in the following releases:

   Linux Platform

     * Sun Java Desktop System (JDS) 2003 with the updated RPMs
       (patch-9400)
     * Sun Java Desktop System (JDS) Release 2 with the updated RPMs
       (patch-9400)

   To download and install the updated RPMs from the update servers,
   select the following from the "launch" bar:

    Launch >> Applications >> System Tools >> Online Update


   A final resolution for the Solaris Platforms is pending completion.
