    Published: 3 Mar 2021Last Modified: 6 Dec 2023

    Summary:

    Details: 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.
