Description
ImageMagick is free and open-source software used for editing and manipulating digital images. In versions below both 7.1.2-19 and 6.9.13-44, Magick frees the memory of the XML tree via the `DestroyXMLTree()` function; however, this process is executed recursively with no depth limit imposed. When Magick processes an XML file with deeply nested structures, it will exhaust the stack memory, resulting in a Denial of Service (DoS) attack. This issue has been fixed in versions 6.9.13-44 and 7.1.2-19.

AI Analysis

Impact

ImageMagick frees the memory of the XML tree through the DestroyXMLTree() function without imposing a depth limit on the recursive cleanup. When an XML document with deeply nested structures is processed, the stack is exhausted, causing the application to terminate. The primary consequence is a denial of service that can prevent the affected software from processing any further images. The weakness is related to uncontrollable recursion and memory exhaustion.

Affected Systems

ImageMagick installations that run versions earlier than 7.1.2‑19 and 6.9.13‑44 are affected. The vulnerability exists in the core ImageMagick product and its .NET bindings such as Magick.NET. Any instance that processes XML input from untrusted sources using these versions is at risk.

Risk and Exploitability

The CVSS score of 7.5 places this issue in the high‑severity range, indicating a significant impact if exploited. While no exploit has been reported in the CISA KEV catalog and the EPSS score is not available, the attack vector is inferred: an attacker can trigger the denial of service by delivering a specially crafted XML file to any ImageMagick instance that accepts untrusted input. The vulnerability is exploitable on a local or remote basis if the ImageMagick engine is invoked by a service exposed to external users.

Remediation

No vendor fix or workaround currently provided.

OpenCVE Recommended Actions

  • Upgrade ImageMagick to version 7.1.2‑19 or later, or 6.9.13‑44 or later.
  • Check that the update has been applied to all binaries, including compiled binaries in environments such as Magick.NET.
  • If an upgrade is not immediately possible, validate or sanitize XML input to limit nesting depth before passing it to ImageMagick.
  • Limit the exposure of services that use ImageMagick to external input, or isolate them behind a firewall to reduce attack surface.
