Update to 8.1.1

• Security

• CVE-2021-25289: The previous fix for CVE-2020-35654 was insufficent due to incorrect error checking in TiffDecode.c.

• CVE-2021-25290: In TiffDecode.c, there is a negative-offset memcpy with an invalid size
• CVE-2021-25291: In TiffDecode.c, invalid tile boundaries could lead to an OOB Read in TiffReadRGBATile
• CVE-2021-25292: The PDF parser has a catastrophic backtracking regex that could be used as a DOS attack.
• CVE-2021-25293: There is an Out of Bounds Read in SGIRleDecode.c, since pillow 4.3.0.

There is an Exhaustion of Memory DOS in the ICNS, ICO, and BLP container formats where Pillow did not properly check the reported size of the contained image. These images could cause arbitrariliy large memory allocations. This was reported by Jiayi Lin, Luke Shaffer, Xinran Xie, and Akshay Ajayan of ASU.edu.
