Summary
In ImageMagick, a vulnerability was found in JP2 handling where an incorrect check leads to a heap buffer over-write of a single byte when certain options are specified. The issue affects versions prior to 6.9.13-48 and 7.1.2-23.
Risk Assessment
The risk involves potential memory corruption, which could lead to application crashes or potential arbitrary code execution by an attacker.
Recommendation
It is recommended to update ImageMagick to version 6.9.13-48 or 7.1.2-23 (or later), which contain the fix.

Original NVD description (English source)
ImageMagick is free and open-source software used for editing and manipulating digital images. Prior to versions 6.9.13-48 and 7.1.2-23, an incorrect check in the JP2 will result in an heap buffer over-write of a single byte when specifying certain options. This issue has been patched in versions 6.9.13-48 and 7.1.2-23.
