Amazon Linux AMI Security Advisory: ALAS-2020-1336
Advisory Release Date: 2020-01-15 21:43 Pacific
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 )
Go before 1.12.10 and 1.13.x before 1.13.1 allow HTTP Request Smuggling.(CVE-2019-16276 )
Run yum update golang to update your system.
