Description

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.

In this particular case the DSA_verify function was fixed with MDVSA-2009:002, this update does however address the RSA_verify function (CVE-2009-0265).
