vulnerability :
- 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(CVE-2020-35512)
