    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.
