Description:
 Multiple race conditions in smtpd.py in the smtpd module in Python 2.6,
 2.7, 3.1, and 3.2 alpha allow remote attackers to cause a denial of service
 (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.
