NVD Description

Note: Versions mentioned in the description apply only to the upstream dbus-daemon package and not the dbus-daemon package as distributed by Centos. See How to fix? for Centos:8 relevant fixed versions and status.

A use-after-free flaw was found in D-Bus Development branch <= 1.13.16, dbus-1.12.x stable branch <= 1.12.18, and dbus-1.10.x and older branches <= 1.10.30 when a system has multiple usernames sharing the same UID. When a set of policy rules references these usernames, D-Bus may free some memory in the heap, which is still used by data structures necessary for the other usernames sharing the UID, possibly leading to a crash or other undefined behaviors
