Debian: DSA-2426-1: gimp security update
Summary
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.
