Updated ImageMagick packages that correct several security issues are now available.

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 security flaws were discovered in the way ImageMagick decodes DCM, PALM, and SGI graphic files. An attacker may be able to execute arbitrary code on a victim's machine if they were able to trick the victim into opening a specially crafted image file (CVE-2006-5456, CVE-2006-5868).

A heap overflow flaw was found in ImageMagick. An attacker may be able to execute arbitrary code on a victim's machine if they were able to trick the victim into opening a specially crafted file (CVE-2006-2440). This issue only affected the version of ImageMagick distributed with Red Hat Enterprise Linux 4.

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

SecurityFocus reports about ImageMagick :

ImageMagick is prone to a remote heap-based buffer-overflow vulnerability because the application fails to properly bounds-check user-supplied input before copying it to an insufficiently sized memory buffer.

Exploiting this issue allows attackers to execute arbitrary machine code in the context of applications that use the ImageMagick library.

Several remote vulnerabilities have been discovered in Imagemagick, a collection of image manipulation programs, which may lead to the execution of arbitrary code. The Common Vulnerabilities and Exposures project identifies the following problems :

  - CVE-2006-0082     Daniel Kobras discovered that Imagemagick is vulnerable     to format string attacks in the filename parsing code.

  - CVE-2006-4144     Damian Put discovered that Imagemagick is vulnerable to     buffer overflows in the module for SGI images.

  - CVE-2006-5456     M Joonas Pihlaja discovered that Imagemagick is     vulnerable to buffer overflows in the module for DCM and     PALM images.

  - CVE-2006-5868     Daniel Kobras discovered that Imagemagick is vulnerable     to buffer overflows in the module for SGI images.

This update also addresses regressions in the XCF codec, which were introduced in the previous security update.

Multiple buffer overflows in ImageMagick before 6.2.9 allow user-assisted attackers to execute arbitrary code via crafted XCF images. (CVE-2006-3743)

Multiple integer overflows in ImageMagick before 6.2.9 allows user-assisted attackers to execute arbitrary code via crafted Sun bitmap images that trigger heap-based buffer overflows.
(CVE-2006-3744)

Integer overflow in the ReadSGIImage function in sgi.c in ImageMagick before 6.2.9 allows user-assisted attackers to cause a denial of service (crash) and possibly execute arbitrary code via large (1) bytes_per_pixel, (2) columns, and (3) rows values, which trigger a heap-based buffer overflow. (CVE-2006-4144)

The updated packages have been patched to correct these issues.

Multiple buffer overflows in Imagemagick 6.0 before 6.0.6.2, and 6.2 before 6.2.4.5, has unknown impact and user-assisted attack vectors via a crafted SGI image.

Updated packages have been patched to correct this issue.

Daniel Kobras discovered multiple buffer overflows in ImageMagick's SGI file format decoder. By tricking a user or an automated system into processing a specially crafted SGI image, this could be exploited to 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.
