RedHat: RHSA-2018-1199:01 Important: patch security update
Summary
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).
Patch should be installed because it is a common way of upgrading
applications.
Security Fix(es):
* patch: Malicious patch files cause ed to execute arbitrary commands
(CVE-2018-1000156)
