3. Description:

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)

Note: If the web browser plug-in provided by the icedtea-web package was
installed, the issues exposed via Java applets could have been exploited
without user interaction if a user visited a malicious website.

4. Solution:

For details on how to apply this update, which includes the changes
described in this advisory, refer to:

https://access.redhat.com/articles/11258

All running instances of OpenJDK Java must be restarted for this update to
take effect.

5. Bugs fixed (https://bugzilla.redhat.com/):

1327743 - CVE-2016-0686 OpenJDK: insufficient thread consistency checks in ObjectInputStream (Serialization, 8129952)
1327749 - CVE-2016-0687 OpenJDK: insufficient byte type checks (Hotspot, 8132051)
1328022 - CVE-2016-0695 OpenJDK: insufficient DSA key parameters checks (Security, 8138593)
1328040 - CVE-2016-3425 OpenJDK: incorrect handling of surrogate pairs in XML attribute values (JAXP, 8143167)
1328210 - CVE-2016-3427 OpenJDK: unrestricted deserialization of authentication credentials (JMX, 8144430)
