gimp - several

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 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.
