ImageMagick is free and open-source software used for editing and manipulating digital images. In versions prior to 7.1.2-0 and 6.9.13-26, in ImageMagicks magick mogrify command, specifying multiple consecutive %d format specifiers in a filename template causes internal pointer arithmetic to generate an address below the beginning of the stack buffer, resulting in a stack overflow through vsnprintf(). Versions 7.1.2-0 and 6.9.13-26 fix the issue.
The product writes to a buffer using an index or pointer that references a memory location prior to the beginning of the buffer.
