Description Tomas Hoger 2020-10-19 09:49:10 UTC 
A flaw was found in the way the Libraries component of OpenJDK handled blacklists of untrusted certificates.  Alternate certificate encodings were not considered, causing certain certificate fingerprints to not be blacklisted, possibly leading to untrusted certificates being accepted.
