"It was discovered that the ObjectInputStream class in the
Serialization component of OpenJDK failed to properly ensure thread
consistency when deserializing serialized input. An untrusted Java
application or applet could use this flaw to bypass Java sandbox
restrictions. (CVE-2016-0686)

It was discovered that the Hotspot component of OpenJDK did not
properly handle byte types. An untrusted Java application or applet
could use this flaw to corrupt Java virtual machine memory and
possibly execute arbitrary code, bypassing Java sandbox restrictions.
(CVE-2016-0687)

It was discovered that the RMI server implementation in the JMX
component in OpenJDK did not restrict which classes can be
deserialized when deserializing authentication credentials. A remote,
unauthenticated attacker able to connect to a JMX port could possibly
use this flaw to trigger deserialization flaws. (CVE-2016-3427)

It was discovered that the JAXP component in OpenJDK failed to
properly handle Unicode surrogate pairs used as part of the XML
attribute values. Specially crafted XML input could cause a Java
application to use an excessive amount of memory when parsed.
(CVE-2016-3425)

It was discovered that the Security component in OpenJDK failed to
check the digest algorithm strength when generating DSA signatures.
The use of a digest weaker than the key strength could lead to the
generation of signatures that were weaker than expected.
(CVE-2016-0695)

It was discovered that the GCM (Galois/Counter Mode) implementation in
the JCE component of OpenJDK used non-constant time comparison when
comparing GCM authentication tag. A remote attacker could possibly use
this flaw to determine correct value of the authentication tag and
bypass authentication protections of GCM. (CVE-2016-3426)");
