RHEL 5 / 6 / 7 : java-1.6.0-openjdk (RHSA-2016:0723)

critical Nessus Plugin ID 91034

Synopsis

The remote Red Hat host is missing one or more security updates.

Description

An update for java-1.6.0-openjdk is now available for Red Hat Enterprise Linux 5, Red Hat Enterprise Linux 6, and 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-1.6.0-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)

Solution

Update the affected packages.
