ImageMagick is free and open-source software used for editing and manipulating digital images. Prior to version 7.1.2-15, a stack-based buffer overflow exists in the ImageMagick FTXT image reader. A crafted FTXT file can cause out-of-bounds writes on the stack, leading to a crash. Version 7.1.2-15 contains a patch.
