Technical details

An out-of-bounds read vulnerability (CWE-125) exists in ImageMagick's '-sample' operation. The flaw is triggered when a specific offset is provided through the 'sample:offset' define, leading the application to read memory outside of the intended buffer. This is a local attack that requires user interaction, such as a user or automated process attempting to process a malicious image file. Successful exploitation can lead to an application crash (Denial of Service). The issue is addressed in ImageMagick version 7.1.2-19 and Magick.NET version 14.12.0.

Affected products
