Amazon Linux AMI : golang (ALAS-2019-1321)

high Nessus Plugin ID 131241

Language:

Synopsis

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

Description

It was discovered that net/http (through net/textproto) in golang does not correctly interpret HTTP requests where an HTTP header contains spaces before the colon. This could be abused by an attacker to smuggle HTTP requests when a proxy or a firewall is placed behind a server implemented in Go or to filter bypasses depending on the specific network configuration. (CVE-2019-16276)

Solution

Run 'yum update golang' to update your system.
