"Several vulnerabilities were discovered in the OpenJDK JRE related to
information disclosure, data integrity, and availability. An attacker
could exploit these to cause a denial of service or expose sensitive
data over the network. (CVE-2015-2590, CVE-2015-2628, CVE-2015-4731,
CVE-2015-4732, CVE-2015-4733, CVE-2015-4760, CVE-2015-4748)

Several vulnerabilities were discovered in the cryptographic
components of the OpenJDK JRE. An attacker could exploit these to
expose sensitive data over the network. (CVE-2015-2601, CVE-2015-2808,
CVE-2015-4000, CVE-2015-2625, CVE-2015-2613)

As a security improvement, this update modifies OpenJDK behavior to
disable RC4 TLS/SSL cipher suites by default.

As a security improvement, this update modifies OpenJDK behavior to
reject DH key sizes below 768 bits by default, preventing a possible
downgrade attack.

Several vulnerabilities were discovered in the OpenJDK JRE related to
information disclosure. An attacker could exploit these to expose
sensitive data over the network. (CVE-2015-2621, CVE-2015-2632)

A vulnerability was discovered with how the JNDI component of the
OpenJDK JRE handles DNS resolutions. A remote attacker could exploit
this to cause a denial of service. (CVE-2015-4749).

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.");
