In ImageMagick 7.0.6-1, a missing NULL check vulnerability was found in the function ReadMATImage in coders/mat.c, which allows attackers to cause a denial of service (assertion failure) in DestroyImageInfo in image.c.

Weakness

The product contains an assert() or similar statement that can be triggered by an attacker, which leads to an application exit or other behavior that is more severe than necessary.

Affected Software

Name Vendor Start Version End Version
Imagemagick Imagemagick 7.0.6-1 7.0.6-1

Extended Description

While assertion is good for catching logic errors and reducing the chances of reaching more serious vulnerability conditions, it can still lead to a denial of service. For example, if a server handles multiple simultaneous connections, and an assert() occurs in one single connection that causes all other connections to be dropped, this is a reachable assertion that leads to a denial of service.
