The extension parser may take quadratic time when parsing a header containing an unclosed string parameter value whose content is a repeating two-byte sequence of a backslash and some other character. This could be abused by an attacker to conduct Regex Denial Of Service (ReDoS) on a single-threaded server by providing a malicious payload with the Sec-WebSocket-Extensions header.</p> <p><strong>Affected:</strong> websocket-extensions (ruby)</p> <p>websocket-extensions ruby module prior to 0.1.5 allows Denial of Service (DoS) via Regex Backtracking.
