NVD Description

Note: Versions mentioned in the description apply only to the upstream katello-client-bootstrap package and not the katello-client-bootstrap package as distributed by RHEL. See How to fix? for RHEL:7 relevant fixed versions and status.

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.
