How to fix?

There is no fixed version for RHEL:7 golang-src.

NVD Description

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

The x/text package before 0.3.3 for Go has a vulnerability in encoding/unicode that could lead to the UTF-16 decoder entering an infinite loop, causing the program to crash or run out of memory. An attacker could provide a single byte to a UTF16 decoder instantiated with UseBOM or ExpectBOM to trigger an infinite loop if the String function on the Decoder is called, or the Decoder is passed to golang.org/x/text/transform.String.
