CVE-2009-0265 (http://nvd.nist.gov/nvd.cfm?cvename=CVE-2009-0265):
  Internet Systems Consortium (ISC) BIND 9.6.0 and earlier does not
  properly check the return value from the OpenSSL EVP_VerifyFinal
  function, which allows remote attackers to bypass validation of the
  certificate chain via a malformed SSL/TLS signature, a similar
  vulnerability to CVE-2008-5077 and CVE-2009-0025.
