How to fix?

Upgrade ImageMagick/ImageMagick to version 6.9.10-69, 7.0.9-0 or higher.

Overview

Affected versions of this package are vulnerable to Out-of-bounds Read. TIFFGetProfiles() in /coders/tiff.c calls strstr() which causes a large out-of-bounds read when it searches for "dc:format=\"image/dng\" within profile due to improper string handling, when a crafted input file is provided to ImageMagick. The patch uses a StringInfo type instead of a raw C string to remedy this. This could cause an impact to availability of the application. This flaw affects ImageMagick versions prior to 7.0.9-0.
