Description
ImageMagick is free and open-source software used for editing and manipulating digital images. Prior to versions 7.1.2-16 and 6.9.13-41, a heap-use-after-free vulnerability exists in the MSL encoder, where a cloned image is destroyed twice. The MSL coder does not support writing MSL so the write capability has been removed. This vulnerability is fixed in 7.1.2-16 and 6.9.13-41.
Affected products
- ImageMagick: before 6.9.13-41; from 7.0.0-0 before 7.1.2-16 — fixed in 6.9.13-41, 7.1.2-16
How to fix
Upgrade to a fixed version: ImageMagick 6.9.13-41, 7.1.2-16. Check the vendor advisory for mitigations.
