Summary
ImageMagick before 7.1.2-26 and 6.9.13-51 contains a memory leak in the ICON decoder that occurs when a memory allocation fails. Processing a crafted ICON file that triggers an allocation failure leaks memory, which may lead to a denial of service.
A flaw was found in ImageMagick. A remote attacker could exploit a memory leak in the ICON decoder by providing a specially crafted ICON file.
When the file is processed, a memory allocation failure occurs, leading to memory exhaustion. This can result in a denial of service (DoS), making the affected system or application unavailable.
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.

Mitigation checklist
- Do not process untrusted image files with ImageMagick. The ICON coder can be disabled in ImageMagick's policy.xml if not needed: `<policy domain="coder" rights="none" pattern="ICON"/>`. Upgrade to ImageMagick 7.1.2-26 or 6.9.13-51 mitigates the issue.
