| The Java Runtime Environment (JRE) component in Oracle Java SE 7
Update 17 and earlier, 6 Update 43 and earlier, and 5.0 Update 41 and
earlier; and OpenJDK 6 and 7; allows remote attackers to execute
arbitrary code via vectors related to AWT, as demonstrated by Ben
Murphy during a Pwn2Own competition at CanSecWest 2013. NOTE: the
previous information is from the April 2013 CPU. Oracle has not
commented on claims from another vendor that this issue is related to
invocation of the system class loader by the
sun.awt.datatransfer.ClassLoaderObjectInputStream class, which allows
remote attackers to bypass Java sandbox restrictions.
