12.10.xCn prior to 12.10.xC8W2. It is, therefore, affected by a
multiple vulnerabilities :

  - A vulnerability, known as SWEET32, exists in the OpenSSL
    component in the 3DES and Blowfish algorithms due to the
    use of weak 64-bit block ciphers by default. A
    man-in-the-middle attacker who has sufficient resources
    can exploit this vulnerability, via a 'birthday' attack,
    to detect a collision that leaks the XOR between the
    fixed secret and a known plaintext, allowing the
    disclosure of the secret text, such as secure HTTPS
    cookies, and possibly resulting in the hijacking of an
    authenticated session. (CVE-2016-2183)

  - A remote code execution vulnerability exists in the Open
    Admin Tool that allows an unauthenticated, remote
    attacker to execute arbitrary code with administrator
    privileges. (CVE-2017-1092)

  - A denial of service vulnerability exists due to an
    overflow condition in the FORMAT_UNITS() function caused
    by improper validation of user-supplied input. An
    authenticated, remote attacker can exploit this to write
    large assertion failure files to the server, resulting
    in a crash of the server. Note that this vulnerability
    only affects the 12.10 version branch. (CVE-2017-1310)");
