RHEL 8 : patch (RHSA-2020:1852)

medium Nessus Plugin ID 143013

Synopsis

The remote Red Hat host is missing a security update for patch.

Description

The remote Redhat Enterprise Linux 8 host has a package installed that is affected by a vulnerability as referenced in the RHSA-2020:1852 advisory.

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)
