Heap Buffer Overflow in ImageMagick

Publication date: 2026-10-08

Last updated on: 2026-10-08

Assigner: VulnCheck

Description
ImageMagick before 7.1.2-31 contains a heap buffer overflow vulnerability that allows attackers to overwrite heap memory by making a crafted call to the GetVirtualPixels API. Attackers can trigger the out-of-bounds heap write through crafted input to crash the server, causing a denial of service.

Exploitability

CWE

KEV
KEV Icon
CWE ID Description
CWE-190 The product performs a calculation that can produce an integer overflow or wraparound when the logic assumes that the resulting value will always be larger than the original value. This occurs when an integer value is incremented to a value that is too large to store in the associated representation. When this occurs, the value may become a very small or negative number.

Executive Summary

This is a heap buffer overflow vulnerability in ImageMagick versions before 7.1.2-31. Attackers exploit it by sending crafted input to the GetVirtualPixels API, causing an out-of-bounds heap write. This leads to memory corruption and crashes, resulting in denial-of-service conditions.

Detection Guidance

To detect this vulnerability, check the installed version of ImageMagick on your system. Run the command 'convert --version' or 'magick --version' to see the version number. If the version is before 7.1.2-31, the system is vulnerable.

Impact Analysis

The vulnerability can cause system crashes and denial-of-service by corrupting heap memory. It requires local access but no privileges or user interaction. Systems running vulnerable ImageMagick versions are at risk of unexpected failures.

Compliance Impact

This vulnerability primarily causes denial-of-service conditions by crashing servers through heap memory corruption. It does not directly lead to data breaches or unauthorized access, which are key concerns for GDPR and HIPAA compliance. However, repeated crashes could disrupt system availability, potentially violating service-level agreements or operational requirements in regulated environments.

Mitigation Strategies

Immediately update ImageMagick to version 7.1.2-31 or later. This patched version addresses the heap buffer overflow issue in the GetVirtualPixels API.
