Amazon Linux AMI : golang (ALAS-2020-1417)

medium Nessus Plugin ID 140092

Language:

Synopsis

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

Description

The version of golang installed on the remote host is prior to 1.13.14-1.58. It is, therefore, affected by a vulnerability as referenced in the ALAS-2020-1417 advisory.

 Go before 1.13.13 and 1.14.x before 1.14.5 has a data race in some net/http servers, as demonstrated by the httputil.ReverseProxy Handler, because it reads a request body and writes a response at the same time.
 A flaw was found Go's net/http package. Servers using ReverseProxy from net/http in the Go standard library are vulnerable to a data race that results in a denial of service. The highest threat from this vulnerability is to system availability. (CVE-2020-15586)

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.
