Attack profile from CVSS 4.0 · CNA. Fix status from CNA and Red Hat. Impact type from CWE-284.
Summary
ImageMagick before 6.9.13-56 and 7.x before 7.1.2-31 lacks a security policy check in the CUT encoder, so configured security policies can be bypassed. A local attacker without privileges can supply crafted input to the CUT encoder to crash the application or leak sensitive data. The flaw is classified as improper access control (CWE-284).
