Description Pedro Sampaio 2017-09-01 13:25:32 EDT

The WriteTHUMBNAILImage function in coders/thumbnail.c in ImageMagick through 8.0.6-10 allows an attacker to cause a denial of service (buffer over-read) by sending a crafted JPEG file.

WriteTHUMBNAILImage function, where an externally controllable value is being used as an index in the process of generating a thumbnail image can also lead to potential Buffer Overflow.
