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: Chris Evans Security Advisory (CESA) 2004.003 at [2]http://scary.beasts.org/security/CESA-2004-003.txt CAN-2004-0687 at [3]http://www.cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2004-0687 CAN-2004-0688 at [4]http://www.cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2004-0688 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.
