critical Nessus Plugin ID 94977

Language:

Synopsis

The remote Amazon Linux AMI host is missing a security update.

Description

It was discovered that the Libraries component of OpenJDK did not restrict the set of algorithms used for JAR integrity verification.
This flaw could allow an attacker to modify content of the JAR file that used weak signing key or hash algorithm. (CVE-2016-5542)

A flaw was found in the way the JMX component of OpenJDK handled classloaders. An untrusted Java application or applet could use this flaw to bypass certain Java sandbox restrictions. (CVE-2016-5554)

A flaw was found in the way the Networking component of OpenJDK handled HTTP proxy authentication. A Java application could possibly expose HTTPS server authentication credentials via a plain text network connection to an HTTP proxy if proxy asked for authentication.
(CVE-2016-5597)

It was discovered that the Hotspot component of OpenJDK did not properly check received Java Debug Wire Protocol (JDWP) packets. An attacker could possibly use this flaw to send debugging commands to a Java program running with debugging enabled if they could make victim's browser send HTTP requests to the JDWP port of the debugged application. (CVE-2016-5573)

It was discovered that the Hotspot component of OpenJDK did not properly check arguments of the System.arraycopy() function in certain cases. An untrusted Java application or applet could use this flaw to corrupt virtual machine's memory and completely bypass Java sandbox restrictions. (CVE-2016-5582)

Solution

Run 'yum update java-1.7.0-openjdk' to update your system.
