remote denial of service vulnerabilities :

  - A flaw exists when handling specially crafted filenames
    that could result in corruption of the FSFS repository.
    A workaround exists to install a pre-commit hook that
    will prevent unsanitized filenames from being committed
    into the repository. (CVE-2013-1968)

    handled aborted connection message are handled as
    critical errors. (CVE-2013-2112)");
