CVE-2021-27923: Pillow Denial of Service by Uncontrolled Resource Consumption
(updated )
Pillow before 8.1.1 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.
