Description Tomas Hoger 2019-08-07 12:27:20 UTC

IBM JDK 8 SR5 FP40 (8.0.5.40) fixes a flaw described by upstream as:

Eclipse OpenJ9 could allow a local attacker to gain elevated privileges on the system, caused by an out-of-bounds write in the String.getBytes method. An attacker could exploit this vulnerability to corrupt memory and write to any 32-bit address or beyond the end of a byte array within Java code run under a SecurityManager.
