Doc Text:
A flaw was found in ImageMagick, a widely used software for image editing. Specifically, an integer overflow occurs during the despeckle operation, which can lead to a heap buffer overflow on 32-bit systems. This vulnerability allows an attacker to cause an out-of-bounds write, potentially resulting in a denial of service (DoS) by making the application crash or become unresponsive.

Description OSIDB Bzimport 2026-04-13 22:01:58 UTC 
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.
