It was discovered that the Hotspot component of OpenJDK did not properly check for integer overflows when generating range check loop predicates. An untrusted Java application or applet could use this flaw to corrupt JVM memory and cause it to crash or, possibly, execute arbitrary code, bypassing Java sandbox restrictions.

It was discovered that the Nashorn JavaScript engine in the Scripting component of OpenJDK could allow JavaScripts to access Java APIs even when access to Java APIs was disabled. An untrusted JavaScript executed by Nashorn could use this flaw to bypass intended restrictions.

It was discovered that the JAR (Java ARchive) verifier in the Security component of OpenJDK did not correctly handle files inside archives with missing digest. An attacker could possibly use this flaw to manipulate content of a singed JAR, bypassing intended verification.

It was discovered that the JPEGImageReader implementation in the 2D component of OpenJDK would, in certain cases, read all image data even if that was not used later. A specially crafted image could cause a Java application to temporarily use an excessive amount of CPU and memory.

A flaw was found in the way the Hotspot component of OpenJDK processed extraneous brackets in function signatures. An untrusted Java application or applet could use this flaw to bypass Java certain sandbox restrictions.
