Subject: Requesting CVE-ID(s) for Python's pip

I would also like to request CVE assignment(s) for two issues in pip
(https://github.com/pypa/pip/), related to Donald Stufft's.

First issue:
------------
  Python's pip versions 1.4.x and earlier are vulnerable to an Arbitrary Code
  Execution Attack due to incorrect regexp parsing of external download links
  in the following functions in pip/index.py:

    * PackageFinder._get_pages() https://github.com/pypa/pip/blob/1.3.X/pip/index.py#L232
    * PackageFinder._sort_links() https://github.com/pypa/pip/blob/1.3.X/pip/index.py#L272
    * PackageFinder._package_versions() https://github.com/pypa/pip/blob/1.3.X/pip/index.py#L285
    * PackageFinder._link_package_versions() https://github.com/pypa/pip/blob/1.3.X/pip/index.py#L290

  Which allow an attacker with the ability to Man-in-the-Middle external
  package URIs (which often include external HTTP URIs, and can include the
  module author's personal website, see
  https://github.com/pypa/pip/commit/a3584d176697bd4c83390de1857679d44389e00d#L0L265)
  to specify an arbitrarily high package version number and gain code
  execution.

                              https://github.com/pypa/pip/issues/425#issuecomment-20640890

  Other mentions: https://github.com/pypa/pip/commit/9ccd5f0bb37508f03e6a19be58af7384eede2157
                  https://paste.debian.net/7309/

  This issue is fixed in pip>=1.5.x by Donald Stufft in the following commits:
  https://github.com/pypa/pip/commit/0e1da584f418ae0088b43d01248572e2ff53d3a1
  https://github.com/pypa/pip/commit/9ccd5f0bb37508f03e6a19be58af7384eede2157

Second issue:
-------------
  Python's pip versions 1.5.x and earlier use MD5 hashes for verification of
  package integrity against PyPI (which defaults to providing MD5).

These issues appear to be unrelated to Donald Stufft's CVE ID request filed
earlier today, and additionally unrelated to the following already assigned
CVEs:

  * CVE-2013-1888 Pip builds in /tmp 
    https://security-tracker.debian.org/tracker/CVE-2013-1888
    https://bugzilla.redhat.com/show_bug.cgi?id=923974
    http://seclists.org/oss-sec/2013/q1/704

  * CVE-2013-1629 Pip<1.3.0 uses a default package index without SSL
    https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2013-1629
    https://bugzilla.redhat.com/show_bug.cgi?id=968059
