Updated ImageMagick packages that correct several security issues are now
available for CentOS Linux version 2.1.
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) 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 with the privileges of the user running ImageMagick.. (CVE-2008-1097) All users of ImageMagick should upgrade to these updated packages, which contain backported patches to correct these issues.
