Core Security Technologies Advisory 2010.0427

Core Security Technologies Advisory - Prior to MS10-024 the Windows SMTP Service generated DNS queries with trivially guessable values in the transaction ID field. The issue was addressed in MS10-024 by adding a call to the 'CAsyncDns::GenerateRandWord' method when building the DNS query. Prior to MS10-024 the Windows SMTP Service did not check that the value of the ID field of a DNS response received from the network actually matched the value of the ID field of a corresponding DNS query packet previously sent. The issue was addressed in MS10-024 by adding validation logic to the 'CAsyncDns::ProcessReadIO' method.
