An update for patch is now available for Red Hat Enterprise Linux 7.6
Extended Update Support.

Red Hat Product Security has rated this update as having a security impact
of Important. A Common Vulnerability Scoring System (CVSS) base score,

3. Description:

The patch program applies diff files to originals. The diff command is used

file).
