Description

It was discovered that the Hotspot component of OpenJDK did not properly check arguments of the System.arraycopy() function in certain cases. An attacker could use this to bypass Java sandbox restrictions. (CVE-2016-5582)

It was discovered that OpenJDK did not restrict the set of algorithms used for Jar integrity verification. An attacker could use this to modify without detection the content of a JAR file, affecting system integrity. (CVE-2016-5542)

It was discovered that the JMX component of OpenJDK did not sufficiently perform classloader consistency checks. An attacker could use this to bypass Java sandbox restrictions. (CVE-2016-5554)

It was discovered that the Hotspot component of OpenJDK did not properly check received Java Debug Wire Protocol (JDWP) packets. An attacker could use this to send debugging commands to a Java application with debugging enabled. (CVE-2016-5573)

It was discovered that OpenJDK did not properly handle HTTP proxy authentication. An attacker could use this to expose HTTPS server authentication credentials. (CVE-2016-5597).

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
