virtualenv: Insecure temporary file usage An insecure temporary file usage has been reported in virtualenv, possibly allowing symlink attacks. virtualenv 2012-06-22 2012-06-22 395285 local 1.5.1 1.5.1

virtualenv is a virtual Python environment builder.

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

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

There is no known workaround at this time.

All virtualenv users should upgrade to the latest version:

# emerge --sync # emerge --ask --oneshot --verbose ">=dev-python/virtualenv-1.5.1" CVE-2011-4617 ackle ackle
