Several vulnerabilities have been identified in GIMP, the GNU Image
Manipulation Program.

CVE-2010-4540
        Stack-based buffer overflow in the load_preset_response
        function in plug-ins/lighting/lighting-ui.c in the "LIGHTING
        EFFECTS > LIGHT" plugin allows user-assisted remote attackers
        to cause a denial of service (application crash) or possibly
        execute arbitrary code via a long Position field in a plugin
        configuration file.

CVE-2010-4541
        Stack-based buffer overflow in the loadit function in
        plug-ins/common/sphere-designer.c in the SPHERE DESIGNER
        plugin allows user-assisted remote attackers to cause a denial
        of service (application crash) or possibly execute arbitrary
        code via a long "Number of lights" field in a plugin
        configuration file.

CVE-2010-4542
        Stack-based buffer overflow in the gfig_read_parameter_gimp_rgb
        function in in the GFIG plugin allows user-assisted remote
        attackers to cause a denial of service (application crash) or
        possibly execute arbitrary code via a long Foreground field in a
        plugin configuration file.

CVE-2010-4543
        Heap-based buffer overflow in the read_channel_data function in
        file-psp.c in the Paint Shop Pro (PSP) plugin allows remote
        attackers to cause a denial of service (application crash) or
        possibly execute arbitrary code via a PSP_COMP_RLE (aka RLE
        compression) image file that begins a long run count at the end
        of the image.

CVE-2011-1782
        The correction for CVE-2010-4543 was incomplete.

CVE-2011-2896
        The LZW decompressor in the LZWReadByte function in
        plug-ins/common/file-gif-load.c does not properly handle code
        words that are absent from the decompression table when
        encountered, which allows remote attackers to trigger an
        infinite loop or a heap-based buffer overflow, and possibly
        execute arbitrary code, via a crafted compressed stream.


For the stable distribution (squeeze), these problems have been fixed in
version 2.6.10-1+squeeze3.

For the testing distribution (wheezy) and the unstable distribution
(sid), these problems have been fixed in version 2.6.11-5.

We recommend that you upgrade your gimp packages.
