cfengine package (vicf, cfmailfilter, and cfcron) create and use
temporary files in an insecure way. A local attacker could exploit
this with a symlink attack to create or overwrite arbitrary files with
the privileges of the user running the cfengine program.

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