Sun(sm) Alert Notification

      * Sun Alert ID: 57645
      * Synopsis: Security Vulnerabilities in imlib Library May Allow a
        Remote Unprivileged User to Execute Arbitrary Code
      * Category: Security
      * Product: Sun Java Desktop System (JDS)
      * BugIDs: 5099934
      * Avoidance: Patch
      * State: Resolved
      * Date Released: 17-Sep-2004
      * Date Closed: 17-Sep-2004
      * Date Modified:

1. Impact

    Due to multiple vulnerabilities in imlib, a remote unprivileged user
    may be able to execute arbitrary code with the privileges of a local
    user when that local user has loaded a bitmap (.bmp) format image file
    supplied by an untrusted remote user.

    Note: imlib is a multi-image format library. It is used in many
    popular Open Source projects such as GNOME 1.x. This interface has
    been deprecated in the GNOME 2.x environment.

    These issues are described in the following documents:

      * CAN-2004-0802 at
        [2]http://www.cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2004-0802

        [3]http://www.cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2004-0817

2. Contributing Factors

    These issues can occur in the following releases:

    Linux Platform

      * Sun Java Desktop System (JDS) 2003 without the updated RPMs
        (patch-9338)
      * Sun Java Desktop System (JDS) Release 2 without the updated RPMs
        (patch-9338)

    Note: JDS for Solaris is not impacted by these issues.

    These issues only occur with imlib versions imlib-1.9.10-781 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 imlib, the following command can be run:

     % rpm -qf /usr/lib/libgdk_imlib.so.1
     imlib-1.9.10-78


3. Symptoms

    There are no reliable symptoms that would show the described issues
    have been exploited.

4. Relief/Workaround

    To work around the described issues, avoid using imlib based software
    to load bitmap image files.

5. Resolution

    These issues are addressed in the following releases:

    Linux Platform

      * Sun Java Desktop System (JDS) 2003 with the updated RPMs
        (patch-9338)
      * Sun Java Desktop System (JDS) Release 2 with the updated RPMs
        (patch-9338)
