ImageMagick is free and open-source software used for editing and manipulating digital images. In versions below both 7.1.2-19 and 6.9.13-44, a stack overflow vulnerability in ImageMagick's FX expression parser allows an attacker to crash the process by providing a deeply nested expression. This issue has been fixed in versions 6.9.13-44 and 7.1.2-19.
