Description

ImageMagick is free and open-source software used for editing and manipulating digital images. Prior to versions 6.9.13-47 and 7.1.2-22, because of a missing check in the MNG coder it would be possible to read more images than the list limit policy would allow resulting in excessive resource use. This issue has been patched in versions 6.9.13-47 and 7.1.2-22.

Affected products

• ImageMagick: before 6.9.13-47; from 7.0.0-0 before 7.1.2-22 — fixed in 6.9.13-47, 7.1.2-22

How to fix

Upgrade to a fixed version: ImageMagick 6.9.13-47, 7.1.2-22. Check the vendor advisory for mitigations.
