Attack-Flow Graph

Executive Summary

This vulnerability affects ImageMagick, a free and open-source software used for editing and manipulating digital images. Prior to versions 6.9.13-48 and 7.1.2-23, an attacker who can connect to a magick -distribute-cache service may exploit a race condition to hijack a file descriptor in the server process.

Impact Analysis

The vulnerability allows an attacker with local access to the magick -distribute-cache service to hijack a file descriptor in the server process. This could lead to unauthorized access or manipulation of files handled by the ImageMagick service, potentially compromising the confidentiality of data.

Mitigation Strategies

To mitigate this vulnerability, you should upgrade ImageMagick to version 6.9.13-48 or later, or version 7.1.2-23 or later, where the issue has been patched.

Compliance Impact

The vulnerability in ImageMagick allows an attacker to hijack a file descriptor in the server process, leading to a high loss of confidentiality. Such a loss of confidentiality could potentially impact compliance with standards and regulations like GDPR and HIPAA, which require protection of sensitive data and confidentiality.

However, the provided information does not explicitly discuss the direct effects on compliance with these standards or regulations.
