Executive Summary

This vulnerability is a memory leak in ImageMagick's TIFF encoder that occurs when memory allocation fails. It affects versions before 7.1.2-26 and is caused by not releasing memory after use, leading to exhaustion and denial of service.

Detection Guidance

To detect this vulnerability, check the installed version of ImageMagick using the command: convert --version or identify --version. If the version is below 7.1.2-26, the system is vulnerable.

Impact Analysis

This vulnerability primarily impacts system availability. An attacker could exploit it to consume excessive memory, causing the affected application or system to slow down or crash. However, it requires local access and high complexity to exploit, reducing practical risk for most users.

Compliance Impact

This vulnerability has minimal direct impact on compliance with standards like GDPR or HIPAA. It does not affect confidentiality or integrity of data, which are key focus areas for these regulations. The primary concern would be potential service disruption due to denial of service.

Mitigation Strategies

Immediately update ImageMagick to version 7.1.2-26 or later. If updating is not possible, disable TIFF image processing in ImageMagick by modifying the policy.xml file to restrict TIFF operations.
