How to fix?
A fix was pushed into the master branch but not yet published.
Overview
Affected versions of this package are vulnerable to Improper Access Control due to the incorrect handling of TCP bind() and connect() operations in the BestEffort mode. An attacker can bypass intended networking (through landlock.V4, landlock.V5, or self-configured) restrictions by exploiting the lack of proper restrictions in this mode.
This is only exploitable if the user employs Landlock rulesets intended to restrict networking and uses them in best-effort mode.
Note: This vulnerability was fixed in version v0.0.0-20241013234402-fb3ad845df46
