RHSA-2016:0723: Critical: java-1.6.0-openjdk security update

The java-1.6.0-openjdk packages provide the OpenJDK 6 Java Runtime Environmentand the OpenJDK 6 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 tocompletely 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 deserializingauthentication credentials. A remote, unauthenticated attacker able to connectto 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. Speciallycrafted XML input could cause a Java application to use an excessive amount ofmemory 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 digestweaker than the key strength could lead to the generation of signatures thatwere weaker than expected. (CVE-2016-0695)
