Security warning for ffmpeg – risk: high
Risk level: 4 (high)
CVSS Base Score: 7,8
CVSS Temporal Score: 7,4
Remote attack: No
The Common Vulnerability Scoring System (CVSS) is used to assess the severity of vulnerabilities in 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 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 “high” according to the CVSS with a base score of 7.8.
