ImageMagick ReadDCMImage() function buffer overflow

imagemagick-readdcmimage-bo (33376)

High Risk

Description:

ImageMagick is vulnerable to a heap-based buffer overflow, caused by an integer overflow in the ReadDCMImage() function. By creating a malicious DCM image file and persuading a victim to open the file, a remote attacer could overflow a buffer and execute arbitrary code on the system with the privileges of the victim.
