RHEL 5 / 7 : java-1.7.0-openjdk (RHSA-2016:0676)

Critical Nessus Plugin ID 90669

Synopsis

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

Description

An update for java-1.7.0-openjdk is now available for Red Hat Enterprise Linux 5 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-1.7.0-openjdk packages provide the OpenJDK 7 Java Runtime Environment and the OpenJDK 7 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.
