 Overview : The host is installed Python, which is prone to multiple vulnerabilities.
        
 Vulnerability Insight :
 
        The flaws exists due to integer overflow in,
        - hashlib module, which can lead to an unreliable cryptographic digest 
          results.
        - the processing of unicode strings.
        - the PyOS_vsnprintf() function on architectures that do not have a 
          vsnprintf() function.
        - the PyOS_vsnprintf() function when passing zero-length strings can 
          lead to memory corruption.

        Impact : Successful exploitation could potentially causes attackers to 
        execute arbitrary code or create a denial of service condition. 

 Impact Level : Application
 
 Affected Software/OS :
        Python 2.5.2 and prior on Linux (All).

 Fix : Fix is available in the SVN repository,
 http://svn.python.org
