CVE-2023-43669 (GCVE-0-2023-43669)

Vulnerability from cvelistv5 – Published: 2023-09-21 00:00 – Updated: 2024-08-02 19:44

Summary

The Tungstenite crate before 0.20.1 for Rust allows remote attackers to cause a denial of service (minutes of CPU consumption) via an excessive length of an HTTP header in a client handshake. The length affects both how many times a parse is attempted (e.g., thousands of times) and the average amount of data for each parse attempt (e.g., millions of bytes).

Severity

7.5 (High)

GHSA-9MCR-873M-XCXP

Vulnerability from github – Published: 2023-09-21 06:30 – Updated: 2024-02-16 22:38

Summary

Tungstenite allows remote attackers to cause a denial of service

Details

The Tungstenite crate through 0.20.0 for Rust allows remote attackers to cause a denial of service (minutes of CPU consumption) via an excessive length of an HTTP header in a client handshake. The length affects both how many times a parse is attempted (e.g., thousands of times) and the average amount of data for each parse attempt (e.g., millions of bytes).

Severity

7.5 (High)
