A flaw was found in python-pillow. TiffDecode has a heap-based buffer overflow when decoding crafted YCbCr files because of certain interpretation conflicts with LibTIFF in RGBA mode. The previous fix for CVE-2020-35654 was insufficient due to incorrect error checking in TiffDecode.c. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability.

Mitigation

Disable the invoice generation feature to mitigate this vulnerability in Red Hat Quay.
