"The version of Adobe Flash Player installed on the remote Windows host
is equal or prior to version 18.0.0.232. It is, therefore, affected by
multiple vulnerabilities :

  - An unspecified stack corruption issue exists that
    allows a remote attacker to execute arbitrary code.
    (CVE-2015-5567, CVE-2015-5579)

  - A vector length corruption issue exists that allows a
    remote attacker to have an unspecified impact.
    (CVE-2015-5568)

  - A use-after-free error exists in an unspecified
    component due to improperly sanitized user-supplied
    input. A remote attacker can exploit this, via a
    specially crafted file, to deference already freed
    memory and execute arbitrary code. (CVE-2015-5570,
    CVE-2015-5574, CVE-2015-5581, CVE-2015-5584,
    CVE-2015-6682)

  - An unspecified flaw exists due to a failure to reject
    content from vulnerable JSONP callback APIs. A remote
    attacker can exploit this to have an unspecified impact.
    (CVE-2015-5571)

  - An unspecified flaw exists that allows a remote attacker
    to bypass security restrictions and gain access to
    sensitive information. (CVE-2015-5572)

  - An unspecified type confusion flaw exists that allows a
    remote attacker to execute arbitrary code.
    (CVE-2015-5573)

  - A flaw exists in an unspecified component due to
    improper validation of user-supplied input when handling
    a specially crafted file. A remote attacker can exploit
    this to corrupt memory, resulting in a denial of service
    or the execution of arbitrary code. (CVE-2015-5575,
    CVE-2015-5577, CVE-2015-5578, CVE-2015-5580,
    CVE-2015-5582, CVE-2015-5588, CVE-2015-6677)

  - A memory leak issue exists that allows a remote
    attacker to have an unspecified impact. (CVE-2015-5576)

  - A stack buffer overflow condition exists due to improper
    validation of user-supplied input. A remote attacker can
    exploit this to execute arbitrary code. (CVE-2015-5587)

  - An unspecified overflow condition exists due to improper
    validation of user-supplied input. A remote attacker can
    exploit this to execute arbitrary code. (CVE-2015-6676,
    CVE-2015-6678)

  - An unspecified flaw exists that allows a remote attacker
    to bypass same-origin policy restrictions and gain
    access to sensitive information. (CVE-2015-6679)");
