CWE-362  (opens in a new tab)

How to fix?

Upgrade Ubuntu:18.04 policykit-1 to version 0.105-20ubuntu0.18.04.5 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream policykit-1 package and not the policykit-1 package as distributed by Ubuntu. See How to fix? for Ubuntu:18.04 relevant fixed versions and status.

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.
