Description Vasyl Kaigorodov 2014-11-20 07:33:25 EST 
It was reported [1] that the build directory in pip is predictable, so a local DoS is possible simply by creating a /tmp/pip-build-<username>/ directory owned by
someone other than the defined user.
Upstream patch that fixes this (will be included in pip 6.0):
https://github.com/pypa/pip/pull/2122
