How to fix?

Upgrade Amazon-Linux:2018.03 dbus to version 1:1.2.24-7.16.amzn1 or higher.
This issue was patched in ALAS-2012-128.

NVD Description

Note: Versions mentioned in the description apply only to the upstream dbus package and not the dbus package as distributed by Amazon-Linux. See How to fix? for Amazon-Linux:2018.03 relevant fixed versions and status.

libdbus 1.5.x and earlier, when used in setuid or other privileged programs in X.org and possibly other products, allows local users to gain privileges and execute arbitrary code via the DBUS_SYSTEM_BUS_ADDRESS environment variable. NOTE: libdbus maintainers state that this is a vulnerability in the applications that do not cleanse environment variables, not in libdbus itself: "we do not support use of libdbus in setuid binaries that do not sanitize their environment before their first call into libdbus."
