Description Vladimir Lettiev 2010-11-01 10:27:54 MSK
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

fixed in r84289: http://svn.python.org/view?rev=84289&view=rev (not yet backported to 2.6)

"not yet backported to 2.6"

А когда и где будет?
Comment 2 Evgenii Terechkov 2015-11-13 09:26:41 MSK
Я так понимаю, в 2.7 уже починено.
