A number of heap-based buffer overflows have been found in The Gimp affecting the PCX (CVE-2011-1178), SGI, GBR and PAT (CVE-2011-1782) plugins. The update fixes these security issues.

This update fixes buffer overflows in the PSP (CVE-2010-4543, CVE-2011-1782), sphere-designer (CVE-2010-4541), gfig (CVE-2010-4542) and lighting (CVE-2010-4540) plugins.

Note that Tenable Network Security has extracted the preceding description block directly from the Fedora security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Nils Philippsen discovered that GIMP incorrectly handled malformed PSP image files. If a user were tricked into opening a specially crafted PSP image file, an attacker could cause GIMP to crash, or possibly execute arbitrary code with the user's privileges.

This update fixes various overflows :

  + CVE-2011-1178: CVSS v2 Base Score: 6.8     (AV:N/AC:M/Au:N/C:P/I:P/A:P)

  + CVE-2011-1782: CVSS v2 Base Score: 6.8     (AV:N/AC:M/Au:N/C:P/I:P/A:P)

Multiple vulnerabilities was discovered and fixed in gimp :

Stack-based buffer overflow in the 'LIGHTING EFFECTS > LIGHT' plugin in GIMP 2.6.11 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. NOTE: it may be uncommon to obtain a GIMP plugin configuration file from an untrusted source that is separate from the distribution of the plugin itself (CVE-2010-4540).

Stack-based buffer overflow in the SPHERE DESIGNER plugin in GIMP 2.6.11 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. NOTE: it may be uncommon to obtain a GIMP plugin configuration file from an untrusted source that is separate from the distribution of the plugin itself (CVE-2010-4541).

Stack-based buffer overflow in the GFIG plugin in GIMP 2.6.11 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. NOTE: it may be uncommon to obtain a GIMP plugin configuration file from an untrusted source that is separate from the distribution of the plugin itself (CVE-2010-4542).

Heap-based buffer overflow in the read_channel_data function in file-psp.c in the Paint Shop Pro (PSP) plugin in GIMP 2.6.11 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-2010-4543, CVE-2011-1782).

The updated packages have been patched to correct these issues.

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.
