ImageMagick is free and open-source software used for editing and manipulating digital images. Prior to versions 7.1.2-15 and 6.9.13-40, sometimes msl.c fails to update the stack index, so an image is stored in the wrong slot and never freed on error, causing leaks. Versions 7.1.2-15 and 6.9.13-40 contain a patch.
