Amazon Linux 2023 : golang, golang-bin, golang-misc (ALAS2023-2024-666)

high Nessus Plugin ID 202921

Language:

Synopsis

The remote Amazon Linux 2023 host is missing a security update.

Description

It is, therefore, affected by a vulnerability as referenced in the ALAS2023-2024-666 advisory.

The net/http HTTP/1.1 client mishandled the case where a server responds to a request with an Expect:
100-continue header with a non-informational (200 or higher) status. This mishandling could leave a client connection in an invalid state, where the next request sent on the connection will fail. An attacker sending a request to a net/http/httputil.ReverseProxy proxy can exploit this mishandling to cause a denial of service by sending Expect: 100-continue requests which elicit a non-informational response from the backend. Each such request leaves the proxy with an invalid connection, and causes one subsequent request using that connection to fail. (CVE-2024-24791)

Tenable has extracted the preceding description block directly from the tested product security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Run 'dnf update golang --releasever 2023.5.20240722' to update your system.
