ImageMagick: Integer Overflow in JNX decoder causes heap buffer over-write when processing extremly large files on 32-bit builds
Impact
ImageMagick is free and open-source software used for editing and manipulating digital images. In versions prior to both 6.9.13-52 and 7.1.2-27, processing an extremely large JNX file on 32-bit platforms can cause an integer overflow, leading to a heap buffer over-write. This issue has been fixed in versions 6.9.13-52 and 7.1.2-27.
