Multiple vulnerabilities reported for Red Hat Enterprise Linux – Risk: medium
Risk level: 3 (medium)
CVSS Base Score: 5,9
CVSS Temporal Score: 5,2
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 severity of the current vulnerability is classified as “medium” according to the CVSS with a base score of 5.9.
