"This update provides Python 3.4.5, which brings many fixes and
enhancements. The following security issues have been fixed :

  - CVE-2016-1000110: CGIHandler could have allowed setting
    of HTTP_PROXY environment variable based on
    user-supplied Proxy request header. (bsc#989523)

  - CVE-2016-0772: A vulnerability in smtplib could have
    allowed a MITM attacker to perform a startTLS stripping
    attack. (bsc#984751)

  - CVE-2016-5636: A heap overflow in Python's zipimport
    module. (bsc#985177)

  - CVE-2016-5699: A header injection flaw in
    urrlib2/urllib/httplib/http.client. (bsc#985348) The
    update also includes the following non-security fixes :

  - Don't force 3rd party C extensions to be built with

    -Werror=declaration-after-statement. (bsc#951166)

  - Make urllib proxy var handling behave as usual on POSIX.
    (bsc#983582) For a comprehensive list of changes please
    refer to the upstream change log:
    https://docs.python.org/3.4/whatsnew/changelog.html

description block directly from the SUSE security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues."
