Summary
Pillow Denial of Service by Uncontrolled Resource Consumption
Details

Pillow before 8.1.2 allows attackers to cause a denial of service (memory consumption) because the reported size of a contained image is not properly checked for an ICO container, and thus an attempted memory allocation can be very large.
