CVE-2017-17682

In ImageMagick 7.0.7-12 Q16, a large loop vulnerability was found in the function ExtractPostscript in coders/wpg.c, which allows attackers to cause a denial of service (CPU exhaustion) via a crafted wpg image file that triggers a ReadWPGImage call.

Weakness

The product does not properly control the allocation and maintenance of a limited resource.

Potential Mitigations

Mitigation of resource exhaustion attacks requires that the target system either:
The first of these solutions is an issue in itself though, since it may allow attackers to prevent the use of the system by a particular valid user. If the attacker impersonates the valid user, they may be able to prevent the user from accessing the server in question.
The second solution is simply difficult to effectively institute – and even when properly done, it does not provide a full solution. It simply makes the attack require more resources on the part of the attacker.
