Description Gianluca Gabrielli 2021-05-07 15:24:12 UTC 
CVE-2021-28678

BlpImagePlugin did not properly check that reads after jumping to file offsets returned data. This could lead to a denial-of-service where the decoder could be run a large number of times on empty data. This dates to Pillow 5.1.0.
