CVE-2013-1629: Pypa Pip

Medium severity, CVSS 6.8. EPSS: 6.2% chance of exploitation in the next 30 days.

pip before 1.3 uses HTTP to retrieve packages from the PyPI repository, and does not perform integrity checks on package contents, which allows man-in-the-middle attackers to execute arbitrary code via a crafted response to a "pip install" operation.

Affected products

• Pypa Pip: before 1.3 (fixed in 1.3)
