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

critical Nessus Plugin ID 90669

Language:

Synopsis

The remote Red Hat host is missing one or more security updates for java-1.7.0-openjdk.

Description

The remote Redhat Enterprise Linux 5 / 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2016:0676 advisory.

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)

Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Update the RHEL java-1.7.0-openjdk package based on the guidance in RHSA-2016:0676.
