+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]
