There is a local DoS in pip 1.3, 1.3.1, 1.4, 1.4.1, 1.5, 1.5.1, 1.5.2, 1.5.3, 1.5.4, 1.5.5, and 1.5.6. In an attempt to fix CVE-2013-1888 pip modified it's build directories from pip-build to pip-build-<username> and added in checks that would ensure that only a directory owned by the current user would be used. However because the build directory is predictable a local DoS is possible simply by creating a /tmp/pip-build-<username>/ directory owned by someone other than the defined user. This issue has also been reported to the Debian bug tracker as https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=725847. This has been fixed in the develop branch of pip which will be released as pip 6.0. I am not aware of any previous CVE for this issue.  https://pip.pypa.io/  https://pypi.python.org/pypi  https://github.com/pypa/pip/pull/2122 --- Donald Stufft PGP: 7C6B 7C5D 5E2B 6356 A926 F04F 6E3C BCE9 3372 DCFA
