Version Information

Related bugreports: #144091, #143533

Synopsis

Multiple buffer overflows have been discovered in ImageMagick, which could potentially result in the execution of arbitrary code.

2.  Impact Information

Background

ImageMagick is a free software suite to manipulate, convert, and create many image formats.

Description

Tavis Ormandy of the Google Security Team discovered a stack and heap buffer overflow in the GIMP XCF Image decoder and multiple heap and integer overflows in the SUN bitmap decoder. Damian Put discovered a heap overflow in the SGI image decoder.

Impact

An attacker may be able to create a specially crafted image that, when processed with ImageMagick, executes arbitrary code with the privileges of the executing user.

3.  Resolution Information

Workaround

There is no known workaround at this time.
