From Red Hat Security Advisory 2016:0650 :
An update for java-1.8.0-openjdk is now available for 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-1.8.0-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)
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.
