:cve:`2021-27921`, :cve:`2021-27922`, :cve:`2021-27923`: Fix DOS attacks
 | 
						|
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
 | 
						|
 | 
						|
There is an exhaustion of memory DOS attack in BLP, ICNS, ICO images
 | 
						|
where Pillow did not properly check the reported size of the contained image.
 | 
						|
These images could cause arbitrarily large memory allocations.
 | 
						|
 | 
						|
These issues were reported by Jiayi Lin, Luke Shaffer, Xinran Xie and
 | 
						|
Akshay Ajayan of `Arizona State University <https://www.asu.edu/>`_.
