Description

coders/mpc.c in ImageMagick before 7.0.6-1 does not enable seekable streams and thus cannot validate blob sizes, which allows remote attackers to cause a denial of service (application crash) or possibly have unspecified other impact via an image received from stdin.

Affected products

ImageMagick: before 6.9.9-0; from 7.0.0-0 before 7.0.6-1 — fixed in 6.9.9-0, 7.0.6-1

How to fix

Upgrade to a fixed version: ImageMagick 6.9.9-0, 7.0.6-1. Check the vendor advisory for mitigations.
