The remote Mac OS X host has Safari installed. 

Versions of Safari earlier than 6.0.1 are reportedly affected by several issues :

  - A rare condition in the handling of Form Autofill could lead to the disclosure of information from the Address Book 'Me' card that was not included in the Autofill popover. (CVE-2012-3714)

  - A logic issue in the handling of HTTPS URLs in the address bar when pasting text could result in the request being sent over HTTP. (CVE-2012-3715)

  - Numerous issues exist in WebKit.

The remote host has iTunes installed, a popular media player for Windows and Mac OS. 

Versions of iTunes earlier than 10.7 are reportedly affected by multiple memory corruption vulnerabilities in WebKit.

The version of Apple iTunes on the remote host is prior to version 10.7. It is, therefore, affected by multiple memory corruption vulnerabilities in the WebKit component.

The version of Apple iTunes installed on the remote Windows host is older than 10.7 and is, therefore, affected by multiple memory corruption vulnerabilities in WebKit.

The remote host is affected by the vulnerability described in GLSA-201208-03 (Chromium: Multiple vulnerabilities)

    Multiple vulnerabilities have been discovered in Chromium. Please review       the CVE identifiers and release notes referenced below for details.
  Impact :

    A remote attacker could entice a user to open a specially crafted web       site using Chromium, possibly resulting in the execution of arbitrary       code with the privileges of the process, a Denial of Service condition,       disclosure of sensitive information, or other unspecified impact.
  Workaround :

    There is no known workaround at this time.

  - A flaw exists in improper sanitizing of user-supplied inputting resulting in multiple unspecified integer overflows with a specially crafted PDF file. (CVE-2012-2828)

  - An user-after-free flaw is triggered during handling of first letters. No further details have been provided. (CVE-2012-2829)

  - A flaw is triggered when an unspecified NULL pointer dereference occurs in array setting handling. (CVE-2012-2830)

  - A flaw is triggered when a NULL pointer dereference occurs in a PDF image codec. (CVE-2012-2832)

  - An overflow condition occurs when the PDF JS API fails to properly sanitize user-supplied input resulting in a buffer overflow. (CVE-2012-2833)

  - An overflow condition occurs in the Matroska container which fails to properly sanitize user-supplied input resulting in an integer overflow. (CVE-2012-2834)

  - A flaw exists in the way it loads dynamic-link-libraries (DLL). (CVE-2012-2764)

  - A flaw is triggered when an unspecified wild read occurs during the handling of XSL. (CVE-2012-2825)
