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.
