ImageMagick: Integer overflow in despeckle operation causes heap buffer overflow on 32-bit builds

Title source: cna

Description

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, an integer overflow in the despeckle operation causes a heap buffer overflow on 32-bit builds that will result in an out of bounds write. This issue has been fixed in versions 6.9.13-44 and 7.1.2-19.
