Synopsis
========

An insecure temporary file usage has been reported in virtualenv,
possibly allowing symlink attacks.

Background
==========

virtualenv is a virtual Python environment builder.

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

    -------------------------------------------------------------------
     Package              /     Vulnerable     /            Unaffected
    -------------------------------------------------------------------
  1  dev-python/virtualenv        < 1.5.1                    >= 1.5.1

Description
===========

The virtualenv.py script in virtualenv does not handle temporary files
securely.

Impact
======

A local attacker could perform symlink attacks to overwrite arbitrary
files with the privileges of the user running the application.

Workaround
==========

There is no known workaround at this time.

Resolution
==========

All virtualenv users should upgrade to the latest version:

  # emerge --sync
  # emerge --ask --oneshot --verbose ">=dev-python/virtualenv-1.5.1"
