Amazon Linux 2 : golang (ALAS-2021-1694)

high Nessus Plugin ID 152236

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 1.15.14-1. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2-2021-1694 advisory.

A vulnerability was found in archive/zip of the Go standard library. Applications written in Go can panic or potentially exhaust system memory when parsing malformed ZIP files. (CVE-2021-33196)

A flaw was found in golang. A panic can be triggered by an attacker in a privileged network position without access to the server certificate's private key, as long as a trusted ECDSA or Ed25519 certificate for the server exists (or can be issued), or the client is configured with Config.InsecureSkipVerify.
Clients that disable all TLS_RSA cipher suites (that is, TLS 1.0-1.2 cipher suites without ECDHE), as well as TLS 1.3-only clients, are unaffected. (CVE-2021-34558)

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

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

Solution

Run 'yum update golang' to update your system.
