Synopsis

Important: patch security update

Type/Severity

Security Advisory Important

Topic

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, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section.

Description

The patch program applies diff files to originals. The diff command is used to compare an original to a changed file. Diff lists the changes made to the file. A person who has the original file can then use the patch command with the diff file to add the changes to their original file (patching the file).

Security Fix(es):

  • patch: do_ed_script in pch.c does not block strings beginning with a ! character (CVE-2018-20969)

  • patch: OS shell command injection when processing crafted patch files (CVE-2019-13638)
