Multiple vulnerabilities reported for Oracle Java SE – Risk: High

Risk level: 4 (high)
CVSS Base Score: 9,0
CVSS Temporal Score: 7,8
Remoteangriff: Ja

The Common Vulnerability Scoring System (CVSS) is used to assess the vulnerability of computer systems. The CVSS standard makes it possible to compare potential or actual security vulnerabilities based on various criteria in order to better prioritize countermeasures. The attributes “none”, “low”, “medium”, “high” and “critical” are used to determine the severity levels of a vulnerability. The Base Score evaluates the requirements for an attack (including authentication, complexity, privileges, user interaction) and its consequences. With the temporal score, framework conditions that can change over time are taken into account in the evaluation. The severity of the vulnerability discussed here is rated as “high” according to the CVSS with a base score of 9.0.

General recommendations for dealing with IT vulnerabilities

Users of the affected applications should keep them up to date. When security gaps become known, manufacturers are required to fix them as quickly as possible by developing a patch or a workaround. If security patches are available, install them promptly. For information, consult the sources listed in the next section. These often contain further information about the latest version of the software in question as well as the availability of security patches or information about workarounds. If you have any further questions or uncertainties, please contact your responsible administrator. IT security managers should regularly check the sources mentioned to see whether a new security update is available.
