REDHAT-BUG-1242144: Medium severity openjdk vulnerability
It was discovered that GCM (Galois Counter Mode), a mode of operation for symmetric key cryptographic block ciphers, implementation in the Security component of OpenJDK failed to properly perform null check. This could cause crash when application performed encryption using a block cipher in GCM mode.
GCM mode is used in several cipher suites defined for TLS 1.2. Affected code was added to OpenJDK version 8, earlier versions 6 and 7 do not contain it and are therefore unaffected.
