"The version of Oracle Java SE or Java for Business installed on the
remote host is affected by an arbitrary code execution vulnerability
in the Hotspot subcomponent due to an unsafe implementation of the
Reflection API, which improperly processes JSR 292 method handles due
to a lack of enforcement of class loader constraints. A remote
attacker can exploit this, by convincing a user to visit a malicious
web page, to execute arbitrary code outside the Java sandbox.");
