Doc Text:
A flaw was found in ImageMagick, a software suite for editing and manipulating digital images. This vulnerability, an integer truncation/wraparound issue within the viff encoder on 32-bit builds, could lead to an out-of-bounds heap write. An attacker could exploit this by providing a specially crafted image file, potentially causing the application to crash and resulting in a Denial of Service (DoS).

Description OSIDB Bzimport 2026-04-13 21:01:23 UTC
ImageMagick is free and open-source software used for editing and manipulating digital images. In versions below both 7.1.2-189 and 6.9.13-44, the viff encoder contains an integer truncation/wraparound issue on 32-bit builds that could trigger an out of bounds heap write, potentially causing a crash. This issue has been fixed in versions 6.9.13-44 and 7.1.2-19.
