Description

A memory leak will occur in the ICON decoder when an allocation fails.

NVD description

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.
