Synopsis: Moderate: python security update
Advisory ID: SLSA-2016:1626-1

 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.
