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. (CVE-2024-9287)
It was discovered that Python incorrectly handled parsing bracketed hosts.
A remote attacker could possibly use this issue to perform a Server-Side
Request Forgery (SSRF) attack. This issue only affected Ubuntu 14.04 LTS
