CVE-2023-43669

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).

Comment 1 Cathy Hu 2023-09-21 10:24:22 UTC

Unfortunately there is no fix for tungstenite yet, once it is out please consider to version bump to the fixed version.

Affected:
- openSUSE:Factory/warp embeds tungstenite (v0.17.3)

Comment 2 Atri Bhattacharya 2023-12-28 21:51:50 UTC

This is resolved with warp version 0.6.2 that is now in Factory. Thanks for the report.
