Description Tomas Hoger 2020-01-13 15:44:23 UTC
A flaw was found in the way the GssKrb5Base class in the Security component of OpenJDK validated properties of SASL messages included in Kerberos GSSAPI, omitting required token checks.  An remote attacker with ability to manipulate network traffic between server and client using Kerberos GSSAPI could possibly perform message modification that would not be detected during message decoding.
