This vulnerability affects the following products : * 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."  This vulnerability enables remote attackers to bypass validation of the certificate chain.  This vulnerability affects the following products : * FirePass versions 5.5 - 5.5.2 * FirePass versions 6.0 - 6.0.3 * FirePass version 6.1 MITIGATION 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.
