Description

When an allocation fails in the TIFF encoder a small memory leak will occur.

NVD description

ImageMagick before 7.1.2-26 contains a memory leak vulnerability in the TIFF encoder when memory allocation fails. Attackers can trigger allocation failures during TIFF image processing to cause memory exhaustion and denial of service.
