"According to the versions of the emacs packages installed, the EulerOS Virtualization installation on the remote host is
affected by the following vulnerabilities :

  - lisp/gnus/gnus-fun.el in GNU Emacs 24.3 and earlier allows local users to overwrite arbitrary files via a
    symlink attack on the /tmp/gnus.face.ppm temporary file. (CVE-2014-3421)

  - lisp/emacs-lisp/find-gc.el in GNU Emacs 24.3 and earlier allows local users to overwrite arbitrary files
    via a symlink attack on a temporary file under /tmp/esrc/. (CVE-2014-3422)

  - lisp/net/tramp-sh.el in GNU Emacs 24.3 and earlier allows local users to overwrite arbitrary files via a
    symlink attack on a /tmp/tramp.##### temporary file. (CVE-2014-3424)

advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional
