Description Arvid Requate univentionstaff 2017-06-26 15:45:10 CEST
Upstream Debian package version 3.1-2+deb8u1 fixes:

* libffi requests an executable stack allowing attackers to more easily trigger arbitrary code execution by overwriting the stack. Please note that libffi is used by a number of other libraries. This affects libffi version 3.2.1. (CVE-2017-1000376)
