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.

Impact Analysis

The main impact is denial of service due to memory exhaustion. It requires local access and high complexity to exploit but does not affect confidentiality or integrity of data.

Compliance Impact

This vulnerability primarily impacts availability and does not directly affect confidentiality or integrity. Compliance impact would depend on system downtime causing violations of service level agreements or availability requirements.

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.

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.
