Description

Updated java-1.8.0-openjdk packages fix security vulnerabilities:

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).
