      * Sun Alert ID: 57652
      * Synopsis: Security Vulnerabilities in libXpm May Allow a Remote
        Unprivileged User to Execute Arbitrary Code
      * Category: Security
      * Product: Solaris, Sun Java Desktop System (JDS)
      * BugIDs: 5077952, 5105762
      * Avoidance: T-Patch, Patch
      * State: Engineering Complete
      * Date Released: 15-Oct-2004
      * Date Closed:

1. Impact

    Security vulnerabilities in the X Pixmap library (libXpm) may allow a
    remote unprivileged user the ability to execute arbitrary code with
    the privileges of a local user when that local user has loaded a X
    Pixmap (Xpm) format image file supplied by an untrusted user.

    Note: The X Pixmap library (libXpm) is used to manipulate and display
    small images in X windowing systems.

    These issues are described in the following documents:

      * [2]http://scary.beasts.org/security/CESA-2004-003.txt
      * [3]http://www.cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2004-0687

2. Contributing Factors

    These issues can occur in the following releases:

    SPARC Platform

      * Solaris 9

    x86 Platform

      * Solaris 9

    Linux

      * Sun Java Desktop System (JDS) 2003 without the updated RPMs
        (patch-9367)
      * Sun Java Desktop System (JDS) Release 2 without the updated RPMs
        (patch-9367)

    Note: Solaris 8 and earlier versions of Solaris are not affected by
    the described issues.

    These issues only occur on JDS Linux systems with libXpm versions
    XFree86-libs-4.3.0-123 or earlier.

    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 libXpm, the following command can be run:

     % rpm -qf /usr/X11R6/lib/libXpm.so.4.11
     XFree86-libs-4.3.0-123

3. Symptoms

    There are no predictable symptoms that would indicate the described
    issues have been exploited.
