Vulnerability Data
ImageMagick is free and open-source software used for editing and manipulating digital images. Prior to version 7.1.2-23, due to a missing depth check a stack overflow can occur in the fx operation by passing a crafted argument. This issue has…

Mitigating Controls (NIST 800-53 r5) AI
Directly requires applying the vendor patch that adds the missing depth check and eliminates the uncontrolled recursion in the fx operator.
Requires continuous vulnerability scanning to identify installations of ImageMagick prior to 7.1.2-23 that remain exposed to the stack-overflow condition.
Maintains an accurate inventory of ImageMagick components so that affected versions can be located and prioritized for remediation.

Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→CSF cross-walk (authority under review) — links open the control.
Secure SDLC practices directly prevent coding errors such as missing recursion limits or termination conditions.
Runtime monitoring of compute resources can detect excessive consumption caused by uncontrolled recursion.
Vulnerability identification processes can discover and record uncontrolled recursion flaws before deployment.
Capacity monitoring and resource provisioning can absorb or limit the impact of runaway recursion.

Security testing in development can detect excessive recursion via static analysis or fuzzing.
Secure development life cycle requires controls that prevent uncontrolled recursion through design and code review.
Application security requirements can mandate recursion limits or stack-depth checks.
Secure system architecture principles include resource-management and input-validation rules that limit recursion.
Secure coding standards directly prohibit or constrain recursive constructs that could exhaust stack or memory.
Capacity management includes monitoring and limits that mitigate resource exhaustion from runaway recursion.
