Description msiddiqu 2019-04-17 10:27:49 UTC
In ImageMagick 7.0.8-36 Q16, there is a heap-based buffer over-read in the function WriteTIFFImage of coders/tiff.c, which allows an attacker to cause a denial of service or information disclosure via a crafted image file.

Comment 2 Huzaifa S. Sidhpurwala 2019-04-18 06:09:37 UTC
Analysis:

Essentially a heap-based OOB read which can crash the application while reading specially crafted TIFF files. Seems like crash or DoS is the maximum impact, no easy way to read bits of OOB memory in this case.
