                   CVE-2016-5699

                   CVE-2016-1000110

Security Fix(es):



* It was discovered that the Python CGIHandler class did not properly

protect against the HTTP_PROXY variable name clash in a CGI context. A

remote attacker could possibly use this flaw to redirect HTTP requests

performed by a Python CGI script to an attacker-controlled proxy via a

malicious HTTP request. (CVE-2016-1000110)



* It was found that Python's smtplib library did not return an exception

when StartTLS failed to be established in the SMTP.starttls() function. A

man in the middle attacker could strip out the STARTTLS command without

generating an exception on the Python SMTP client application, preventing

the establishment of the TLS layer. (CVE-2016-0772)



* It was found that the Python's httplib library (used by urllib, urllib2

and others) did not properly check HTTPConnection.putheader() function

arguments. An attacker could use this flaw to inject additional headers in

a Python application that allowed user provided header names or values.
