Description
In PolicyKit (aka polkit) 0.115, the "start time" protection mechanism can be bypassed because fork() is not atomic, and therefore authorization decisions are improperly cached. This is related to lack of uid checking in polkitbackend/polkitbackendinteractiveauthority.c.
Weaknesses (CWE)
- CWE-362 — Concurrent Execution using Shared Resource with Improper Synchronization
