Description
Gumlet php-image-resize before 3.0.1 contains a denial of service vulnerability because the ImageResize constructor in lib/ImageResize.php passes images to GD imagecreatefrom* functions without pixel limits. Remote attackers can upload small, highly compressed images that decode to large bitmaps, exhausting PHP memory and terminating the worker process.
