Synopsis
========

Multiple vulnerabilities have been found in Python, the worst of which
could result in a Denial of Service condition.

Background
==========

Python is an interpreted, interactive, object-oriented programming
language.

Affected packages
=================

    -------------------------------------------------------------------
     Package              /     Vulnerable     /            Unaffected

A remote attacker could possibly perform a CRLF injection attack,
obtain sensitive information, trick Python into sending cookies to the
wrong domain or cause a Denial of Service condition.

Workaround
==========

There is no known workaround at this time.

Resolution
==========

All Python 2.7.x users should upgrade to the latest version:

  # emerge --sync
  # emerge --ask --oneshot --verbose ">=dev-lang/python-2.7.17:2.7"

All Python 3.5.x users should upgrade to the latest version:

  # emerge --sync
  # emerge --ask --oneshot --verbose ">=dev-lang/python-3.5.7:3.5/3.5m"

All Python 3.6.x users should upgrade to the latest version:

  # emerge --sync
  # emerge --ask --oneshot --verbose ">=dev-lang/python-3.6.9:3.6/3.6m"

All Python 3.7x users should upgrade to the latest version:

  # emerge --sync
  # emerge --ask --oneshot --verbose ">=dev-lang/python-3.7.4:3.7/3.7m"
