+From e74dd1d96753b0538192143adf58d04fcd3b242b Mon Sep 17 00:00:00 2001
+From: Matthias Gerstner <mgerstner@suse.de>
+Date: Fri, 14 Aug 2020 22:14:36 -0700
+Subject: [PATCH] Correct multiple security issues that are present if the tcsd
+ is started by root instead of the tss user.
+
+Patch fixes the following 3 CVEs:
+
+CVE-2020-24332
+If the tcsd daemon is started with root privileges,
+the creation of the system.data file is prone to symlink attacks
+
+CVE-2020-24330
+If the tcsd daemon is started with root privileges,
+it fails to drop the root gid after it is no longer needed
+
+CVE-2020-24331
+If the tcsd daemon is started with root privileges,
+the tss user has read and write access to the /etc/tcsd.conf file
