"According to its version, the instance of Flash Player installed on
the remote Mac OS X host is 10.3.183.7 or earlier.  It is therefore
reportedly affected by several critical vulnerabilities :

  - Multiple AVM stack overflow vulnerabilities could lead
    to code execution. (CVE-2011-2426, CVE-2011-2427)

  - A logic error issue could lead to code execution or 
    a browser crash. (CVE-2011-2428)

  - A Flash Player security control bypass vulnerability 
    could lead to information disclosure. (CVE-2011-2429)

  - A streaming media logic error vulnerability could lead
    to code execution. (CVE-2011-2430)

  - A universal cross-site scripting vulnerability could be
    abused to take actions on a user's behalf on any 
    website if the user is tricked into visiting a 
    malicious website. Note that this issue is reportedly
    being actively exploited in targeted attacks. 
    (CVE-2011-2444)"
