ImageMagic SGI Buffer Overflow, PSD/TIFF DoS and Filename Format String
------------------------------------------------------------------------
SUMMARY
<http://www.imagemagick.org/> ImageMagickTM, "is a free software suite
for the creation, modification and display of bitmap images".
ImageMagic contain vulnerabilities that allow attacker to cause the
program to execute arbitrary code by exploiting a problem caused by poor
sanitization of the filename and allows attackers to crash ImageMagic by
making it process specially crafted image files.
DETAILS
Vulnerable Systems:
* ImageMagic version 6.1.8 and prior
Immune Systems:
* ImageMagic version 6.2.0
Format String:
The format string vulnerability allows remote attackers to execute code
as the user running display by providing handcrafted filenames of images.
Buffer Overflow:
An heap overflow was found in ImageMagick's SGI parser. It is possible
that an attacker can leverage this to cause the program to execute
arbitrary code by tricking a user into opening a specially crafted SGI
image file.
Denial of Service:
A specially crafted TIFF image or an invalid TIFF tag can be used to cause
ImageMagick to crash. The ImageMagick parser of PSD files can be used to
cause ImageMagic to crash by suppling it with a specially crafted PSD
file.
Vendor Status:
A new version of ImageMagic is available at:
<http://www.imagemagick.org/> http://www.imagemagick.org/.
