Description Tomas Hoger 2018-07-13 15:35:05 UTC

A flaw was found in the GCTR function implementation in the Security component in OpenJDK version 10.  The function is used to implement Galois/Counter Mode (GCM) mode of operation for symmetric block ciphers.  The implementation did not detect counter roll over, leading to an insufficient protection of encrypted data.

Comment 1 Tomas Hoger 2018-07-13 15:36:06 UTC

This only affected OpenJDK 10, which is not currently shipped in Red Hat products.

Public now via Oracle CPU July 2018:

The issue was fixed in Oracle JDK 10.0.2.
