Description

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).

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.
