prior to 7.03 build 108, 8.1x prior to 8.15, or 9.0x prior to 9.06. It
is, therefore, affected by the following vulnerabilities :

  - A security feature bypass vulnerability exists, known as
    Bar Mitzvah, due to improper combination of state data
    with key data by the RC4 cipher algorithm during the
    initialization phase. A man-in-the-middle attacker can
    exploit this, via a brute-force attack using LSB values,
    to decrypt the traffic. (CVE-2015-2808)

  - A flaw exists due to a failure to authenticate users,
    even with Encrypted Control Communications enabled. An
    unauthenticated, remote attacker can exploit this to
    execute arbitrary code. (CVE-2016-2004)

  - Multiple overflow conditions exist due to improper
    validation of user-supplied input. An unauthenticated,
    remote attacker can exploit these issues, via specially
    crafted 'User Name' or 'Domain' field in an EXEC_BAR
    request, to cause a stack-based buffer overflow,
    resulting in a denial of service or the execution of
    arbitrary code. (CVE-2016-2005, CVE-2016-2006)

  - An overflow condition exists due to improper validation
    of user-supplied input. An unauthenticated, remote
    attacker can exploit this, via specially crafted
    EXEC_SCRIPT request, to cause a stack-based buffer
    overflow, resulting in a denial of service or the
    execution of arbitrary code. (CVE-2016-2007)

  - An unspecified flaw exists that allows an
    unauthenticated, remote attacker to disclose sensitive
    information or execute arbitrary code. (CVE-2016-2008)");
