ImageMagick is free and open-source software used for editing and manipulating digital images. Prior to version 7.1.2-26, an incorrect handling of arguments can cause a heap buffer over-write in the JP2 encoder. This issue has been fixed in version7.1.2-26.

A flaw was found in ImageMagick, a free and open-source software for editing and manipulating digital images. An incorrect handling of arguments in the JP2 encoder can lead to a heap buffer overwrite. This vulnerability could allow an attacker to cause a denial of service (DoS) by providing a specially crafted image, leading to an application crash.

Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base or stability.
