Hello gophers,

We have just released Go versions 1.19.1 and 1.18.6, minor point releases.

These minor releases include 2 security fixes following the security policy:

  • net/http: handle server errors after sending GOAWAY

    A closing HTTP/2 server connection could hang forever waiting for a clean shutdown that was preempted by a subsequent fatal error. This failure mode could be exploited to cause a denial of service.

    Thanks to Bahruz Jabiyev, Tommaso Innocenti, Anthony Gavazzi, Steven Sprecher, and Kaan Onarlioglu for reporting this.

    This is CVE-2022-27664 and Go issue https://go.dev/issue/54658.

  • net/url: JoinPath does not strip relative path components in all circumstances

    JoinPath and URL.JoinPath would not remove ../ path components appended to a relative path. For example, JoinPath("https://go.dev", "../go") returned the URL https://go.dev/../go, despite the JoinPath documentation stating that ../ path elements are cleaned from the result.

    Thanks to @q0jt for reporting this issue.

    This is CVE-2022-32190 and Go issue https://go.dev/issue/54385.

Michael and Heschi for the Go team
