Generic extension manager for WebSocket connections. Security Fix(es): websocket-extensions ruby module prior to 0.1.5 allows Denial of Service (DoS) via Regex Backtracking. 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.(CVE-2020-7663) An update for rubygem-websocket-extensions is now available for openEuler-22.03-LTS. openEuler Security has rated this update as having a security impact of high.
