The load_tile function in the XCF coder in coders/xcf.c in (1) ImageMagick 6.2.8-0 and (2) GraphicsMagick (aka gm) 1.1.7 allows user-assisted remote attackers to cause a denial of service (crash) or possibly execute arbitrary code via a crafted .xcf file that triggers an out-of-bounds heap write, possibly related to the ScaleCharToQuantum function.

From Red Hat Security Advisory 2008:0145 :

Updated ImageMagick packages that correct several security issues are now available for Red Hat Enterprise Linux versions 3, 4, and 5.

This update has been rated as having moderate security impact by the Red Hat Security Response Team.

ImageMagick is an image display and manipulation tool for the X Window System that can read and write multiple image formats.

Several heap-based buffer overflow flaws were found in ImageMagick. If a victim opened a specially crafted DCM or XWD file, an attacker could potentially execute arbitrary code on the victim's machine.
(CVE-2007-1797)

Several denial of service flaws were found in ImageMagick's parsing of XCF and DCM files. Attempting to process a specially crafted input file in these formats could cause ImageMagick to enter an infinite loop. (CVE-2007-4985)

Several integer overflow flaws were found in ImageMagick. If a victim opened a specially crafted DCM, DIB, XBM, XCF or XWD file, an attacker could potentially execute arbitrary code with the privileges of the user running ImageMagick. (CVE-2007-4986)

An integer overflow flaw was found in ImageMagick's DIB parsing code.
If a victim opened a specially crafted DIB file, an attacker could potentially execute arbitrary code with the privileges of the user running ImageMagick. (CVE-2007-4988)

A heap-based buffer overflow flaw was found in the way ImageMagick parsed XCF files. If a specially crafted XCF image was opened, ImageMagick could be made to overwrite heap memory beyond the bounds of its allocated memory. This could, potentially, allow an attacker to execute arbitrary code on the machine running ImageMagick.
(CVE-2008-1096)

A heap-based buffer overflow flaw was found in ImageMagick's processing of certain malformed PCX images. If a victim opened a specially crafted PCX file, an attacker could possibly execute arbitrary code on the victim's machine. (CVE-2008-1097)

All users of ImageMagick should upgrade to these updated packages, which contain backported patches to correct these issues.

  - CVE-2009-1882     Integer overflow allows remote attackers to cause a     denial of service (crash) and possibly execute arbitrary     code via a crafted TIFF file, which triggers a buffer     overflow.

Several vulnerabilities have been discovered in the imagemagick image manipulation programs which can lead to the execution of arbitrary code, exposure of sensitive information or cause DoS. The Common Vulnerabilities and Exposures project identifies the following problems :

  - CVE-2007-1667     Multiple integer overflows in XInitImage function in     xwd.c for ImageMagick, allow user-assisted remote     attackers to cause a denial of service (crash) or obtain     sensitive information via crafted images with large or     negative values that trigger a buffer overflow. It only     affects the oldstable distribution (etch).

  - CVE-2007-1797     Multiple integer overflows allow remote attackers to     execute arbitrary code via a crafted DCM image, or the     colors or comments field in a crafted XWD image. It only     affects the oldstable distribution (etch).

  - CVE-2007-4985     A crafted image file can trigger an infinite loop in the     ReadDCMImage function or in the ReadXCFImage function.
    It only affects the oldstable distribution (etch).

  - CVE-2007-4986     Multiple integer overflows allow context-dependent     attackers to execute arbitrary code via a crafted .dcm,     .dib, .xbm, .xcf, or .xwd image file, which triggers a     heap-based buffer overflow. It only affects the     oldstable distribution (etch).

  - CVE-2007-4987     Off-by-one error allows context-dependent attackers to     execute arbitrary code via a crafted image file, which     triggers the writing of a '\0' character to an     out-of-bounds address. It affects only the oldstable     distribution (etch).

  - CVE-2007-4988     A sign extension error allows context-dependent     attackers to execute arbitrary code via a crafted width     value in an image file, which triggers an integer     overflow and a heap-based buffer overflow. It affects     only the oldstable distribution (etch).

  - CVE-2008-1096     The load_tile function in the XCF coder allows     user-assisted remote attackers to cause a denial of     service or possibly execute arbitrary code via a crafted     .xcf file that triggers an out-of-bounds heap write. It     affects only to oldstable (etch).

  - CVE-2008-1097     Heap-based buffer overflow in the PCX coder allows     user-assisted remote attackers to cause a denial of     service or possibly execute arbitrary code via a crafted     .pcx file that triggers incorrect memory allocation for     the scanline array, leading to memory corruption. It     affects only to oldstable (etch).

  - CVE-2009-1882     Integer overflow allows remote attackers to cause a     denial of service (crash) and possibly execute arbitrary     code via a crafted TIFF file, which triggers a buffer     overflow.

A heap-based buffer overflow vulnerability was found in how ImageMagick parsed XCF files. If ImageMagick opened a specially crafted XCF file, it could be made to overwrite heap memory beyond the bounds of its allocated memory, potentially allowing an attacker to execute arbitrary code on the system running ImageMagick (CVE-2008-1096).

Another heap-based buffer overflow vulnerability was found in how ImageMagick processed certain malformed PCX images. If ImageMagick opened a specially crafted PCX image file, an attacker could possibly execute arbitrary code on the system running ImageMagick (CVE-2008-1097).

The updated packages have been patched to correct these issues.

It was discovered that ImageMagick did not correctly handle certain malformed XCF images. If a user were tricked into opening a specially crafted image with an application that uses ImageMagick, an attacker could cause a denial of service and possibly execute arbitrary code with the user's privileges.

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