Description

The remote Ubuntu 14.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-2696-1 advisory.

 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)
