Description

A flaw was found in ImageMagick in coders/hdr.c. An attacker who submits a crafted file that is processed by ImageMagick could trigger undefined behavior in the form of values outside the range of type `unsigned char`. This would most likely lead to an impact to application availability, but could potentially cause other problems related to undefined behavior. This flaw affects ImageMagick versions prior to ImageMagick 7.0.8-68.

ImageMagick: before 6.9.10-68; from 7.0.0-0 before 7.0.8-68 — fixed in 6.9.10-68, 7.0.8-68

How to fix

Upgrade to a fixed version: ImageMagick 6.9.10-68, 7.0.8-68. Check the vendor advisory for mitigations.
