MIT Kerberos Security Advisory – Risk: medium
Risk level: 3 (medium)
CVSS Base Score: 7,5
CVSS Temporal Score: 6,9
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 classified as “medium” according to the CVSS with a base score of 7.5.

General recommendations 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 fix them as quickly as possible by developing a patch or a workaround. If new security updates are available, install them as soon as possible. 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 when the IT security warning Affected manufacturers provide a new security update.
