From 2daf4331a648cc2df6982c1a6ec47a705e038255 Mon Sep 17 00:00:00 2001 From: Radosław Piliszek Date: Mon, 29 Aug 2022 18:13:34 +0000 Subject: Fix writable rootwrap/privsep config Fixes a hypothetical security issue related to privilege escalation via rootwrap/privsep. A potential vulnerable service could previously allow writes to its rootwrap/privsep config and thus allow for more commands to be run with root privileges via rootwrap/privsep. For a succesful attack, this would also require the service to allow to run arbitrary commands via rootwrap/privsep. Thus far, no such vulnerabilities have been reported and thus this fix is simply strengthening the container images against such an issue in the future.
