    Summary: Updated libffi packages fix security vulnerability

    Details: 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, such as the "stack clash" class of vulnerabilities discovered by Qualys Research Labs.
