Multiple race conditions in smtpd.py in the smtpd module in Python 2.6,

(daemon outage) by establishing and then immediately closing a TCP
connection, leading to the accept function having an unexpected return
value of None, an unexpected value of None for the address, or an
ECONNABORTED, EAGAIN, or EWOULDBLOCK error, or the getpeername function
having an ENOTCONN error, a related issue to CVE-2010-3492.
