Description Tomas Hoger 2020-08-05 17:58:32 UTC 
IBM JDK 7 SR10 FP70 (7.0.10.70), 7.1 SR4 FP70 (7.1.4.70), and 8 SR6 FP15 (8.0.6.15) fix a flaw described by upstream as:

Eclipse OpenJ9 could allow a remote attacker to obtain sensitive information, caused by the premature return of the current method with an undefined return value. By invoking the System.arraycopy method with a length longer than the length of the source or destination array can, an attacker could exploit this vulnerability to obtain sensitive information.

IBM also notes that this issue is only applicable to IBM JDK on AIX and Linux on the Power platform.
