CWE-444  (opens in a new tab)

How to fix?

Upgrade RHEL:7 golang-bin to version 0:1.6.3-1.el7_2.1 or higher.
This issue was patched in RHSA-2016:1538.

NVD Description

Note: Versions mentioned in the description apply only to the upstream golang-bin package and not the golang-bin package as distributed by RHEL. See How to fix? for RHEL:7 relevant fixed versions and status.

The net/http library in net/textproto/reader.go in Go before 1.4.3 does not properly parse HTTP header keys, which allows remote attackers to conduct HTTP request smuggling attacks via a space instead of a hyphen, as demonstrated by "Content Length" instead of "Content-Length."
