CVE-2024-9287

A vulnerability has been found in the Python `venv` module and CLI. Path names provided when creating a virtual environment were not quoted properly, allowing the creator to inject commands into virtual environment "activation" scripts, for example, "source venv/bin/activate". This flaw allows attacker-controlled virtual environments to run commands when the virtual environment is activated.

It was discovered that the Python ipaddress module contained incorrect information about which IP address ranges were considered “private” or “globally reachable”. This could possibly result in applications applying incorrect security policies. This issue only affected Ubuntu 14.04 LTS and Ubuntu 16.04 LTS. It was discovered that Python incorrectly handled quoting path names when using the venv module. A local attacker able to control virtual environments could possibly use this issue to execute arbitrary code when the virtual environment is activated.
