Heap Buffer Overflow in ImageMagick

Publication date: 2026-06-10

Last updated on: 2026-06-11

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.

Exploitability

CWE

KEV

CWE ID	Description
CWE-787	The product writes data past the end, or before the beginning, of the intended buffer.
CWE-122	A heap overflow condition is a buffer overflow, where the buffer that can be overwritten is allocated in the heap portion of memory, generally meaning that the buffer was allocated using a routine such as malloc().

Attack-Flow Graph

Compliance Impact

The provided information does not specify any direct impact of this vulnerability on compliance with common standards and regulations such as GDPR or HIPAA.

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.

Detection Guidance

This vulnerability affects ImageMagick versions prior to 7.1.2-25 when processing crafted multi-frame images with the SF3 encoder. To detect if your system is vulnerable, first check the installed ImageMagick version.

Run the command `magick -version` or `convert -version` to determine the installed ImageMagick version.

If the version is older than 7.1.2-25, your system is potentially vulnerable. Since the vulnerability requires local access and crafted multi-frame images, monitoring for unusual crashes or memory corruption during image processing may also indicate exploitation attempts.
