Executive Summary

CVE-2026-56375 is a memory leak vulnerability in ImageMagick's ASHLAR coder. When an action fails, the system does not properly release allocated memory, causing a gradual exhaustion of memory resources. This can lead to a denial of service condition where the application becomes unresponsive or crashes.

Mitigation Strategies

Since no patched versions are available, consider downgrading to a version prior to 7.1.2-18 or disabling the ASHLAR coder in ImageMagick configuration. Monitor memory usage for unexpected spikes.

Impact Analysis

This vulnerability can cause system slowdowns or crashes due to memory exhaustion. It may disrupt services relying on ImageMagick for image processing. Attackers could exploit it by triggering failed actions to force a denial of service on vulnerable systems.

Detection Guidance

To detect this vulnerability, check the installed version of ImageMagick using the command: identify -version. If the output shows a version <= 7.1.2-18, your system is vulnerable.
