"The remote MiracleLinux 7 host has packages installed that are affected by a vulnerability as referenced in the
AXSA:2017-2282:02 advisory.

    * A command injection flaw within the Emacs enriched mode handling has been discovered. By tricking an
    unsuspecting user into opening a specially crafted file using Emacs, a remote attacker could exploit this
    flaw to execute arbitrary commands with the privileges of the Emacs user. (CVE-2017-14482)
    CVE-2017-14482
    GNU Emacs before 25.3 allows remote attackers to execute arbitrary code
    via email with crafted Content-Type: text/enriched data containing an
    x-display XML element that specifies execution of shell commands,
    related to an unsafe text/enriched extension in
    lisp/textmodes/enriched.el, and unsafe Gnus support for enriched and
    richtext inline MIME objects in lisp/gnus/mm-view.el. In particular, an
    Emacs user can be instantly compromised by reading a crafted email
    message (or Usenet news article).

Tenable has extracted the preceding description block directly from the MiracleLinux security advisory.
