(RHSA-2008:0145) Moderate: ImageMagick security update

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.
