Package        : libffi
CVE ID         : CVE-2017-1000376
Debian Bug     : 751907

libffi, a library used to call code written in one language from code written
in a different language, was enforcing an executable stack on the i386
architecture. While this might not be considered a vulnerability by itself,
this could be leveraged when exploiting other vulnerabilities, like for 
example
the "stack clash" class of vulnerabilities discovered by Qualys Research Labs.
For the full details, please refer to their advisory published at:
https://www.qualys.com/2017/06/19/stack-clash/stack-clash.txt

For the oldstable distribution (jessie), this problem has been fixed
in version 3.1-2+deb8u1.

For the stable distribution (stretch), this problem has been fixed in
version 3.2.1-4.

For the testing distribution (buster), this problem has been fixed
in version 3.2.1-4.

For the unstable distribution (sid), this problem has been fixed in
version 3.2.1-4.

We recommend that you upgrade your libffi packages.
