RedHat: RHSA-2020-1852:01 Moderate: patch security and bug fix 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).
Security Fix(es):
* patch: the following of symlinks in inp.c and util.c is mishandled in
cases other than input files (CVE-2019-13636)
