    Package : stunnel4
    CVE ID : CVE-2015-3644
    Debian Bug : 785352

    Johan Olofsson discovered an authentication bypass vulnerability in
    Stunnel, a program designed to work as an universal SSL tunnel for
    network daemons. When Stunnel in server mode is used with the redirect
    option and certificate-based authentication is enabled with "verify = 2"
    or higher, then only the initial connection is redirected to the hosts specified with "redirect". This allows a remote attacker to bypass authentication.

    For the stable distribution (jessie), this problem has been fixed in
    version 3:5.06-2+deb8u1.

    For the testing distribution (stretch), this problem has been fixed
    in version 3:5.18-1.

    For the unstable distribution (sid), this problem has been fixed in
    version 3:5.18-1.

    We recommend that you upgrade your stunnel4 packages.
