Gentoo Linux Security Advisory

Title: ImageMagick: PALM and DCM buffer overflows (GLSA 200611-19)
Severity: normal
Exploitable: remote
Date: November 24, 2006
Bug(s): #152672
ID: 200611-19

Synopsis

ImageMagick improperly handles PALM and DCM images, potentially resulting in the execution of arbitrary code.

Background

ImageMagick is a software suite to create, edit, and compose bitmap images, that can also read, write, and convert images in many other formats.

Affected Packages

Package: media-gfx/imagemagick
Vulnerable: < 6.3.0.5
Unaffected: >= 6.3.0.5
Architectures: All supported architectures


Description

M. Joonas Pihlaja has reported that a boundary error exists within the ReadDCMImage() function of coders/dcm.c, causing the improper handling of DCM images. Pihlaja also reported that there are several boundary errors in the ReadPALMImage() function of coders/palm.c, similarly causing the improper handling of PALM images.

Impact

An attacker could entice a user to open a specially crafted DCM or PALM image with ImageMagick, and possibly execute arbitrary code with the privileges of the user running ImageMagick.

Workaround

There is no known workaround at this time.

Resolution

All ImageMagick users should upgrade to the latest version:
Code:
# emerge --sync
# emerge --ask --oneshot --verbose ">=media-gfx/imagemagick-6.3.0.5"


References

CVE-2006-5456
