CVE-2021-27923

7.5 highEPSS 3.0%

High (7.5). EPSS 3.0% chance of exploitation in the next 30 days. Fixed in pillow 8.1.1, 8.1.2.

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.
