Vulnerability 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 ICNS container, and thus an attempted memory allocation can be very large.

8.1.2
Security

There is an exhaustion of memory DOS in the BLP (CVE-2021-27921), ICNS (CVE-2021-27922) and ICO (CVE-2021-27923) container formats where Pillow did not properly check the reported size of the contained image. These images could cause arbitrarily large memory allocations. This was reported by Jiayi Lin, Luke Shaffer, Xinran Xie, and Akshay Ajayan of Arizona State University.
