Red Hat Security Advisory 2016-0651-01 - The java-1.8.0-openjdk packages provide the OpenJDK 8 Java Runtime Environment and the OpenJDK 8 Java Software Development Kit. Security Fix: 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. 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.

3. Description:
The java-1.8.0-openjdk packages provide the OpenJDK 8 Java Runtime
Environment and the OpenJDK 8 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 GCM (Galois/Counter Mode) implementation in
the JCE component in OpenJDK used a non-constant time comparison when
comparing GCM authentication tags. A remote attacker could possibly use
this flaw to determine the value of the authentication tag. (CVE-2016-3426)
* 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)
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)
1328059 - CVE-2016-3426 OpenJDK: non-constant time GCM authentication tag comparison (JCE, 8143945)
1328210 - CVE-2016-3427 OpenJDK: unrestricted deserialization of authentication credentials (JMX, 8144430)
