New! Vulnerability Priority Rating (VPR)

Tenable calculates a dynamic VPR for every vulnerability. VPR combines vulnerability information with threat intelligence and machine learning algorithms to predict which vulnerabilities are most likely to be exploited in attacks. Read more about what VPR is and how it is different from CVSS.

VPR Score: 6.7


The remote Ubuntu host is missing one or more security-related patches.


It was discovered that the BigDecimal implementation in OpenJDK performed excessive computation when given certain values. An attacker could use this to cause a denial of service (excessive CPU usage).

Corwin de Boor and Robert Xiao discovered that the RMI registry implementation in OpenJDK did not properly select the correct skeleton class in some situations. An attacker could use this to possibly escape Java sandbox restrictions. (CVE-2019-2684)

Mateusz Jurczyk discovered a vulnerability in the 2D component of OpenJDK. An attacker could use this to possibly escape Java sandbox restrictions. This issue only affected OpenJDK 8 in Ubuntu 16.04 LTS.
