What led you to consider it might be a buffer overflow in Exim?
Looks more like your machine was already compromised, and the rootkit
was busy trying to email your group and passwd files to somewhere -
fortunately for you, the script doing the mailing wasn't written to
speak properly synchronised SMTP, and Exim is clever enough to stop it
in its tracks.
Or something....
