Scientific Linux Security Update : python on SL6.x, SL7.x i386/x86_64 (httpoxy)

This script is Copyright (C) 2016 Tenable Network Security, Inc.


Synopsis :

The remote Scientific Linux host is missing one or more security
updates.

Description :

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. (CVE-2016-5699)
