This is from the sendmail 8.12.3 ChangeLog:

        Protect against interrupted select() call when enforcing Milter
                read and write timeouts.  Patch from Gurusamy Sarathy of

This is on the MIMEDefang web site:

    4. Sendmail 8.12.x. The latest version as of this writing is 8.12.3.
       We do not recommend the use of earlier versions of Sendmail, as
       they contain errors in the libmilter code.

...but beyond just that reason, I'd suggest sendmail 8.12.4 and MIMEDefang
2.15 so you know you've got every known bugfix taken care of (without
installing a beta I mean).
