Synopsis

Critical: java-1.8.0-openjdk security update

Type/Severity

Security Advisory: Critical

Topic

An update for java-1.8.0-openjdk is now available for 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.

Description

The java-1.8.0-openjdk packages provide the OpenJDK 8 Java Runtime Environment and the OpenJDK 8 Java Software Development Kit.

Security Fix(es):

• Multiple flaws were discovered in the Hotspot and Libraries components in OpenJDK. An untrusted Java application or applet could use these flaws to completely bypass Java sandbox restrictions. (CVE-2016-3606, CVE-2016-3587, CVE-2016-3598, CVE-2016-3610)
• Multiple denial of service flaws were found in the JAXP component in OpenJDK. A specially crafted XML file could cause a Java application using JAXP to consume an excessive amount of CPU and memory when parsed. (CVE-2016-3500, CVE-2016-3508)
• Multiple flaws were found in the CORBA and Hotsport components in OpenJDK. An untrusted Java application or applet could use these flaws to bypass certain Java sandbox restrictions. (CVE-2016-3458, CVE-2016-3550)

Note: If the web browser plug-in provided by the icedtea-web package was installed, the issues exposed via Java applets could have been exploited without user interaction if a user visited a malicious website.
