Language:

Synopsis

The remote Amazon Linux 2 host is missing a security update.

Description

The version of golang installed on the remote host is prior to 1.15.12-1. It is, therefore, affected by a vulnerability as referenced in the ALAS2-2021-1657 advisory.

 A vulnerability was found in net/http of the Go standard library when parsing very large HTTP header values, causing a crash and subsequent denial of service. This vulnerability affects both clients and servers written in Go, however servers are only vulnerable if the default 1 MB value for MaxHeaderBytes is increased. (CVE-2021-31525)

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 'yum update golang' to update your system.
