Heap Buffer Overflow in ImageMagick

Publication date: 2026-06-10

Last updated on: 2026-06-10

Assigner: GitHub, Inc.

Description
ImageMagick is free and open-source software used for editing and manipulating digital images. Prior to version 7.1.2-25, a crafted multi-frame can result in a heap buffer over-write when encoding it with the SF3 encoder. This issue has been patched in version 7.1.2-25.

Executive Summary

This vulnerability exists in ImageMagick, a free and open-source software used for editing and manipulating digital images. Prior to version 7.1.2-25, a specially crafted multi-frame image can cause a heap buffer overwrite when it is encoded using the SF3 encoder. This means that the software may write data beyond the allocated memory buffer, potentially leading to crashes or other unintended behavior. The issue has been fixed in version 7.1.2-25.

Impact Analysis

The vulnerability can lead to a heap buffer overwrite, which may cause the ImageMagick application to crash or behave unpredictably when processing crafted multi-frame images with the SF3 encoder. According to the CVSS score (6.2), the impact is primarily on availability (A:H), meaning it can cause denial of service. There is no direct impact on confidentiality or integrity.

Mitigation Strategies

To mitigate this vulnerability, you should upgrade ImageMagick to version 7.1.2-25 or later, where the issue has been patched.
