CentOS Errata and Security Advisory CESA-2016:0723
The java-1.6.0-openjdk packages provide the OpenJDK 6 Java Runtime Environment
and 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 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)
