Attack-Flow Graph

Executive Summary

This vulnerability exists in ImageMagick versions before 7.1.2-19 and is caused by an off-by-one error in morphology validation. This error allows out-of-bounds heap buffer reads. Specifically, attackers can trigger a heap buffer overflow by providing incorrect morphology parameters, which leads to single pixel memory access violations.

Impact Analysis

The vulnerability can lead to heap buffer overflow, which may cause memory corruption or crashes in applications using vulnerable versions of ImageMagick. This could potentially be exploited by attackers to disrupt service or cause unexpected behavior in software that processes images using the affected ImageMagick versions.
