This PR has been flagged for autoclosing. However, it is being skipped due to the branch being already modified. Please close/delete it manually or report a bug if you think this is in error.
This PR contains the following updates:
0.1.3->0.1.4GitHub Vulnerability Alerts
CVE-2020-7662
Impact
The ReDoS flaw allows an attacker to exhaust the server's capacity to process incoming requests by sending a WebSocket handshake request containing a header of the following form:
That is, a header containing an unclosed string parameter value whose content is a repeating two-byte sequence of a backslash and some other character. The parser takes exponential time to reject this header as invalid, and this will block the processing of any other work on the same thread. Thus if you are running a single-threaded server, such a request can render your service completely unavailable.
Patches
Users should upgrade to version 0.1.4.
Workarounds
There are no known work-arounds other than disabling any public-facing WebSocket functionality you are operating.
