"An update for java-1.7.0-openjdk is now available for Red Hat
Enterprise Linux 5 and Red Hat Enterprise Linux 7.

Red Hat Product Security has rated this update as having a security
impact of Critical. A Common Vulnerability Scoring System (CVSS) base
score, which gives a detailed severity rating, is available for each
vulnerability from the CVE link(s) in the References section.

The java-1.7.0-openjdk packages provide the OpenJDK 7 Java Runtime
Environment and the OpenJDK 7 Java Software Development Kit.

Security Fix(es) :

* Multiple flaws were discovered in the Serialization and Hotspot
components in OpenJDK. An untrusted Java application or applet could
use these flaws to completely bypass Java sandbox restrictions.
(CVE-2016-0686, 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)");
