Description Tomas Hoger 2020-01-13 16:15:55 UTC
It was discovered that the Kerberos implementation in the Security component of OpenJDK used RSA-MD5 checksum in Ticket Granting Service (TGS) requests even though MD5 algorithm is no longer considered safe for such use case.  A remote attacker could possibly use this flaw to manipulate TGS requests.
