CVE-2019-6133 (opens in a new tab)How to fix?
Upgrade Centos:6 polkit-devel to version 0:0.96-11.el6_10.1 or higher.
NVD Description
Note: Versions mentioned in the description apply only to the upstream polkit-devel package and not the polkit-devel package as distributed by Centos.
See How to fix? for Centos:6 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.
