The remote host is affected by the vulnerability described in GLSA-201403-05 (GNU Emacs: Multiple vulnerabilities)
Multiple vulnerabilities have been discovered in GNU Emacs:
When ‘global-ede-mode’ is enabled, EDE in Emacs automatically loads a Project.ede file from the project directory (CVE-2012-0035).
When ‘enable-local-variables’’ is set to ‘:safe’, Emacs automatically processes eval forms (CVE-2012-3479).
Impact :
A remote attacker could entice a user to open a specially crafted file, possibly resulting in execution of arbitrary code with the privileges of the process or a Denial of Service condition.
Workaround :
There is no known workaround at this time.
