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.
