    'initialize' heap buffer 'arg_types' allocation is made

    this array size after mentioned allocation and cause
    heap overflow.(CVE-2016-2339)

  - Type confusion exists in _cancel_eval Ruby's TclTkIp
    class method. Attacker passing different type of object
    than String as 'retval' argument can cause arbitrary
    code execution.(CVE-2016-2337)

vulnerabilities :

  - An exploitable heap overflow vulnerability exists in

    functionality of Ruby. In Fiddle::Function.new
    'initialize' heap buffer 'arg_types' allocation is made
    based on args array length. Specially constructed
    object passed as element of args array can increase
    this array size after mentioned allocation and cause
    heap overflow.(CVE-2016-2339)

  - Type confusion exists in _cancel_eval Ruby's TclTkIp
    class method. Attacker passing different type of object
    than String as 'retval' argument can cause arbitrary
    code execution.(CVE-2016-2337)

description block directly from the EulerOS security advisory. Tenable
has attempted to automatically clean and format it as much as possible

validate the hostname returned in the SRV record before sending
requests to it. (CVE-2015-3900)

CVE-2015-3900 , which allowed redirection to an arbitrary gem server
