CVE-2023-43669 SUSE CVE security@suse.de SUSE Security Team SUSE CVE-2023-43669 Interim 1 17 2026-03-05T03:36:03Z current 2023-09-21T23:18:21Z 2026-03-05T03:36:03Z cve-database/bin/generate-cvrf-cve.pl 2020-12-27T01:00:00Z CVE-2023-43669 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).
