Description

The cgrulesengd daemon in libcgroup creates log files with world readable and writable permissions due to a reset of the file mode creation mask (umask(0)).

For Debian 8 'Jessie', this problem has been fixed in version 0.41-6+deb8u1.

We recommend that you upgrade your libcgroup packages.

NOTE: Tenable Network Security has extracted the preceding description block directly from the DLA security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
