It was discovered that the IIOPInputStream class in the CORBA component of OpenJDK failed to properly check object and field types during object deserialization. An untrusted Java application or applet could use this flaw to bypass Java sandbox restrictions.

It was discovered that ICU Layout Engine was missing multiple boundary and error return checks. These could lead to buffer overflows and memory corruption. A specially crafted font file could cause an application using ICU to parse untrusted fonts to crash and, possibly, execute arbitrary code.

ICU code is embedded the 2D component in OpenJDK and used by FontManager. An untrusted Java application or applet could use this flaw to execute arbitrary code with Java Virtual Machine privileges and bypass Java sandbox restrictions.

It was discovered that the DGCImpl (for RMI distributed garbage-collection - DGC) class in the RMI component of OpenJDK failed to use restricted access control context when processing untrusted input. An untrusted Java application or applet could use this flaw to bypass Java sandbox restrictions.

It was discovered that the ObjectStreamClass in the Serialization component of OpenJDK failed to ensure that the object is fully initialized before allowing calls of certain methods. An untrusted Java application or applet could use this flaw to bypass Java sandbox restrictions.

It was discovered that the DGCClient (for RMI distributed garbage-collection - DGC) class in the RMI component of OpenJDK failed to use restricted access control context when handling JRMP (Java Remote Method Protocol) messages. An untrusted Java application or applet could use this flaw to bypass Java sandbox restrictions.

Multiple integer overflow issues were found in the implementation of Buffers in the java.nio (Non-blocking I/O) packages in the Libraries component of OpenJDK. These could lead to out of bounds buffer access and Java Virtual Machine memory corruption. An untursted Java application or applet could use these flaws to run arbitrary code with the Java Virtual Machine privileges or bypass Java sandbox restrictions.

It was discovered that the StubGenerator class in the CORBA component of OpenJDK failed to generate code with all needed permission checks related to object (de-)serialization. An untursted Java application or applet could use this flaw to bypass Java sandbox restrictions.
