Cyrus IMAP Server contains a flaw related to the TLS implementation failing to properly clear transport layer buffers when changing from plaintext to ciphertext upon receipt of the 'STARTTLS' command. This may allow a remote attacker to inject arbitrary plaintext data which will be executed upon transition to ciphertext.
