Amazon Linux 2 : golang (ALAS-2021-1657)

medium Nessus Plugin ID 150968

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.

 - net/http in Go before 1.15.12 and 1.16.x before 1.16.4 allows remote attackers to cause a denial of service (panic) via a large header to ReadRequest or ReadResponse. Server, Transport, and Client can each be affected in some configurations. (CVE-2021-31525)

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.
