ImageMagick before 6.9.13-57 and 7.x before 7.1.2-32 contains an information disclosure vulnerability in the JPEG decoder, which performs a read that exposes uninitialized memory when handling crafted input. Attackers can supply a crafted JPEG file for processing to disclose uninitialized memory contents.
