From 0d88b73d189ea3440ccaab00418d6469f76fa590 Mon Sep 17 00:00:00 2001

Subject: [PATCH] cgrulesengd: remove umask(0)
One of our partners has noticed that cgred daemon is creating a log file
(/var/log/cgred) with too wide permissions (0666) and that is seen as
a security bug because an untrusted user can write to otherwise
restricted area. CVE-2018-14348 has been assigned to this issue.
CVE: CVE-2018-14348
Upstream-Status: Backport [https://sourceforge.net/p/libcg/libcg/ci/0d88b73d189ea3440ccaab00418d6469f76fa590]
