Security Advisory for KDE – Risk: medium
Risk level: 5 (medium)
CVSS Base Score: 7,8
CVSS Temporal Score: 6,8
Remote Attack: No
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 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. According to the CVSS, the risk of the vulnerability discussed here is rated as “medium” with a base score of 7.8.
