Summary

ImageMagick is free and open-source software used for editing and manipulating digital images. Prior to versions 6.9.13-48 and 7.1.2-23, an attacker who can connect to a magick -distribute-cache service can cause a heap buffer over-write in the server process. This issue has been patched in versions 6.9.13-48 and 7.1.2-23.
