Multiple vulnerabilities for Python – risk: medium
Risk level: 3 (medium)
CVSS Base Score: 6,5
CVSS Temporal Score: 5,7
Remoteangriff: Ja
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 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 current vulnerability is classified as “medium” according to the CVSS with a base score of 6.5.
Python Bug: Description of the attack
Python is a universal, commonly interpreted, high-level programming language.
A remote, anonymous attacker can exploit several vulnerabilities in Python to perform a denial of service attack and information disclosure.
The vulnerabilities were classified using the CVE reference system (Common Vulnerabilities and Exposures) based on the individual serial numbers CVE-2021-3737 and CVE-2021-4189.
