ImageMagick before 7.1.2-26 and 6.9.13-51 contains a heap-based buffer over-write vulnerability that occurs when running an X11 import with a crafted window title, which can result in heap memory corruption and denial of service.

Red Hat Enterprise Linux ships ImageMagick in RHEL 6 ELS and RHEL 7 ELS. This flaw has been rated as having a Low security impact and is not currently planned to be addressed in future updates of those products. For additional information, refer to the Issue Severity Classification: https://access.redhat.com/security/updates/classification/. Do not use ImageMagick's X11 import command with untrusted window titles. The X11 import functionality requires a running X11 display and is not typically used in server-side image processing pipelines. Upgrade to ImageMagick 7.1.2-26 or 6.9.13-51 mitigates the issue.
