CVE-2021-27922

Published: 03 March 2021

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.

Notes

AuthorNote

while this is mentioned in the 8.1.1 release notes, it doesn't
seem to be mentioned in the CHANGES file, and I can't seem to
locate the commits that fix this in 8.1.1 vs 8.1.0
This was actually fixed in 8.1.2.
