"The remote Redhat Enterprise Linux 6 / 7 host has packages installed that are affected by multiple vulnerabilities as
referenced in the RHSA-2016:1630 advisory.

    Python is an interpreted, interactive, object-oriented programming language, which includes modules,
    classes, exceptions, very high level dynamic data types and dynamic typing. Python supports interfaces to
    many system calls and libraries, as well as to various windowing systems.

    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)

    Red Hat would like to thank Scott Geary (VendHQ) for reporting CVE-2016-1000110.

Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version
number.");
