DescriptionCVE.org

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.

AnalysisAI

Stack exhaustion in ImageMagick's XML tree parser allows remote unauthenticated attackers to trigger denial-of-service conditions by submitting specially crafted XML files with deeply nested structures. Affects all versions below 6.9.13-44 and 7.1.2-19 across multiple platforms including the Magick.NET wrapper. EPSS score of 0.04% (12th percentile) indicates low observed exploitation probability, though the network-accessible attack vector (AV:N) and lack of authentication requirements (PR:N) present theoretical risk for internet-facing deployments processing untrusted XML input.

Technical ContextAI

ImageMagick processes various image formats including those embedding XML metadata (SVG, MVG, MSL). The vulnerability resides in the DestroyXMLTree() cleanup function in the XML parsing library, which implements recursive memory deallocation without stack depth guards. CWE-674 (Uncontrolled Recursion) manifests when the parser traverses deeply nested XML structures during cleanup operations. Each recursion level consumes stack frames until the process exhausts available stack memory, typically 8MB on Linux systems or 1MB on Windows, causing abrupt termination. This affects both the C/C++ ImageMagick core (CPE cpe:2.3:a:imagemagick:imagemagick) and downstream projects like Magick.NET that wrap the native library.

RemediationAI

Upgrade to ImageMagick 6.9.13-44 or later for 6.x deployments, or 7.1.2-19 or later for 7.x deployments. The fix implemented in commit ccdc01180276aa2cb3d4a32a611aa4f417061cd8 adds recursion depth limits to DestroyXMLTree() to prevent stack exhaustion. For Magick.NET users, upgrade to version 14.12.0 or later which incorporates the patched native library (https://github.com/dlemstra/Magick.NET/releases/tag/14.12.0). As a temporary workaround for environments unable to immediately patch, implement application-layer XML input validation to reject files with excessive nesting depth (recommend maximum 100-200 levels), disable processing of XML-based image formats (SVG, MVG, MSL) via policy.xml configuration if not required, or isolate ImageMagick processing in resource-limited containers with stack size restrictions to prevent broader system impact.
