PUBLISHED
CVSS 7.5 HIGH
Record from OSV · Published March 3, 2021
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.
