Sun(sm) Alert Notification
      * Sun Alert ID: 101776
      * Synopsis: Security Vulnerabilities in The " libgdk_pixbuf" Library
        May Allow a Remote Unprivileged User the ability to Execute
        Arbitrary Code
      * Category: Security
      * Product: GNOME 2.0 Desktop, Sun Java Desktop System 2003
      * BugIDs: 5103573
      * Avoidance: Patch, Workaround
      * State: Workaround
      * Date Released: 23-Jun-2005
      * Date Closed:
      * Date Modified:

1. Impact

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

    The libgdk_pixbuf library is part of the GIMP Toolkit (GTK+) and is
    used for loading and rendering images.

    These issues are described in the following documents:
      * http://www.cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2004-0782
      * http://www.cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2004-0783

2. Contributing Factors

    These issues can occur in the following releases:

    SPARC Platform:
      * GNOME 2.0 (for Solaris 8) without patch 114644-03
      * GNOME 2.0 (for Solaris 9) without patch 114686-03
      * GNOME 2.0.2 (for Solaris 9)without patch 115738-04

    x86 Platform
      * GNOME 2.0 (for Solaris 8) without patch 114645-03
      * GNOME 2.0 (for Solaris 9) without patch 114687-03
      * GNOME 2.0.2 (for Solaris 9)
      * Solaris 9 with JDS release 2 installed

    Linux
      * Sun Java Desktop System (JDS) 2003 without the updated RPMs
        (patch-118903-01)
      * Sun Java Desktop System (JDS) Release 2 without the updated RPMs
        (patch-118905-01)

    Note: Solaris 10 is not affected by these issues.

    To determine the version of GNOME that is currently installed on the
    system, the following command can be run (output will vary by
    platform):
     % grep description /usr/share/gnome/gnome-about/gnome-version.xml
     <description>fcs-10b</description> for GNOME 2.0 releases
     <description>2.0.0_patch-us2</description>

    Alternatively (for the same results), in a terminal window from within
    the GNOME desktop, the following command can be run:
     % /usr/bin/gnome-about

    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 - 2003

    To determine if JDS release 2 is installed on a Solaris 9 system, the
    following command can be run:
     % grep distributor-version /usr/share/gnome-about/gnome-version.xml
     <distributor-version>Sun Java Desktop System, Release 2</distributor-versio
n>

    To determine the version of GTK on JDS for Linux systems, run the
    following command:
     % rpm -qf /usr/lib/gtk-2.0/2.2.0/loaders/libpixbufloader-xpm.so
     gtk2-2.2.2-30


3. Symptoms

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

4. Relief/Workaround

    To work around the described issues, do not load XPixmap (Xpm) images
    from untrusted sources.

5. Resolution

    These issues are addressed in the following releases:

    SPARC Platform
      * GNOME 2.0 (for Solaris 8) with patch 114644-03 or later
      * GNOME 2.0 (for Solaris 9) with patch 114686-03 or later
      * GNOME 2.0.2 (for Solaris 9)with patch 115738-04 or later

    x86 Platform
      * GNOME 2.0 (for Solaris 8) with patch 114645-03 or later
      * GNOME 2.0 (for Solaris 9) with patch 114687-03 or later

    Linux
      * Sun Java Desktop System (JDS) 2003 with the updated RPMs
        (patch-118903-01)
      * Sun Java Desktop System (JDS) Release 2 with the updated RPMs
        (patch-118905-01)

    To download and install the updated RPMs from the update servers,
    select the following sequence from the "launch" bar:
     Launch >> Applications >> System Tools >> Online Update
