Multiple vulnerabilities reported for Oracle Java SE – risk: medium
Risk level: 4 (medium)
CVSS Base Score: 5,9
CVSS Temporal Score: 5,2
Remoteangriff: Ja
The Common Vulnerability Scoring System (CVSS) is used to assess the severity of security vulnerabilities in computer systems. The CVSS standard makes it possible to compare potential or actual security gaps based on various metrics in order to create a priority list based on this for initiating countermeasures. The attributes “none”, “low”, “medium”, “high” and “critical” are used for the severity of a vulnerability. The base score assesses the prerequisites for an attack (including authentication, complexity, privileges, user interaction) and its consequences. The Temporal Score also takes into account changes over time with regard to the risk situation. The severity of the current vulnerability is classified as “medium” according to the CVSS with a base score of 5.9.

General measures for dealing with IT security gaps
Users of the affected applications should keep them up to date. When security gaps become known, manufacturers are required to remedy them as quickly as possible by developing a patch or a workaround. If security patches are available, install them as soon as possible. For information, consult the sources listed in the next section. These often contain further information on the latest version of the software in question and the availability of security patches or tips on workarounds. If you have any further questions or are unsure, contact your responsible administrator. IT security managers should regularly check when the manufacturing company makes a new security update available.
