Multiple vulnerabilities for QT – Risk: medium
Risk level: 5 (medium)
CVSS Base Score: 7,6
CVSS Temporal Score: 6,6
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 metrics in order to better prioritize 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. With the temporal score, framework conditions that change over time are included in the evaluation. The risk of the vulnerability discussed here is classified as “medium” according to the CVSS with a base score of 7.6.

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 remedy them as quickly as possible by developing a patch or a workaround. If new security updates become available, install them as soon as possible. For information purposes, 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.
