Uncontrolled Resource Consumption
Imgix through 2019-06-19 allows remote attackers to cause a denial of service (resource consumption) by manipulating a small JPEG file to specify dimensions of 64250x64250 pixels, which is mishandled during an attempt to load the 'whole image' into memory.
CWE-400 - Uncontrolled resource consumption
An uncontrolled resource allocation attack (also known as resource exhaustion attack) triggers unauthorized overconsumption of the limited resources in an application, such as memory, file system storage, database connection pool entries, and CPU. This may lead to denial of service for valid users and degradation of the application's functionality as well as that of the host operating system.
