        Security vulnerabilities have been identified in f5 FirePass and 
        BIG-IP SAM.


        The vendor has provided the following information regarding these
        1. "Vulnerabilities in Microsoft Active Template Library (ATL) 
        could allow remote code execution and may result in memory 
        corruption, information disclosure, and instantiation of objects 
        without regard to security policy." [1]
        This vulnerability affects the following products [1]: 
          * BIG-IP SAM version 8.0
          * FirePass versions 5.5 - 5.5.2
          * FirePass versions 6.0 - 6.0.3
        2. "OpenSSL 0.9.8i and earlier does not properly check the return 
        value from the EVP_VerifyFinal function." [2]
        This vulnerability enables remote attackers to bypass validation
        of the certificate chain. [3]
        This vulnerability affects the following products [2]:
          * FirePass versions 5.5 - 5.5.2
          * FirePass versions 6.0 - 6.0.3
          * FirePass version 6.1


        The vulnerability for Microsoft Active Template Library has been 
        fixed for FirePass appliances in version 6.1.0 and is scheduled 
        to be fixed in future versions for BIG-IP SAM.
        The second vulnerability for OpenSSL did not have a patch at the 
        time of this publication. The vendor has stated "FirePass versions 
        listed as subject to this vulnerability allow DSA certificates and 
        keys to be installed, however, by default they do not use DSA 
        certificates and keys and are not vulnerable to this issue."
        Until such a time as a patch is made available, administrators
        may wish to consider not using DSA certificates and keys.
