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)");
