Vulnerability Data

ImageMagick is free and open-source software used for editing and manipulating digital images. Prior to versions 7.1.2.23 and 6.9.13-48, a crafted MSL image can trigger a heap-use-after-free. Versions 7.1.2.23 and 6.9.13-48 fix the issue.

MITRE ATT&CK Enterprise TechniquesAI

T1190 Exploit Public-Facing Application Initial Access
Adversaries may attempt to exploit a weakness in an Internet-facing host or system to initially access a network.

T1204.003 Malicious Image Execution
Adversaries may rely on a user running a malicious image to facilitate execution.

Why these techniques?

Use-after-free in ImageMagick image processing enables RCE via crafted MSL images, directly facilitating server-side exploitation (T1190) or malicious image delivery (T1204.003).

Mitigating Controls (NIST 800-53 r5) AI

SI-2 Flaw Remediation good match
prevent

Directly requires applying the vendor patch that eliminates the heap use-after-free in MSL processing.

SI-10 Information Input Validation partial match
prevent

Input validation on image files can reject or sanitize malformed MSL content before it reaches the vulnerable parser.

SI-7 Software, Firmware, and Information Integrity partial match
detect

Integrity verification of ImageMagick binaries and libraries can detect unauthorized or tampered versions containing the flaw.
