Description

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.

Affected products

• ImageMagick: before 6.9.10-69; from 7.0.0-0 before 7.0.9-0 — fixed in 6.9.10-69, 7.0.9-0

How to fix

Upgrade to a fixed version: ImageMagick 6.9.10-69, 7.0.9-0. Check the vendor advisory for mitigations.
