Severity: normal

Date: June 22, 2012
Bug(s): #395285
ID: 201206-17

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: dev-python/virtualenv
Vulnerable: < 1.5.1
Unaffected: >= 1.5.1
Architectures: All supported architectures


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