3. Description:

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.
