There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - An issue was discovered in dbus >= 1.3.0 before 1.12.18. The DBusServer in libdbus, as used in dbus-
 daemon, leaks file descriptors when a message exceeds the per-message file descriptor limit. A local

 this to make the system service reach its file descriptor limit, denying service to subsequent D-Bus
 clients. (CVE-2020-12049)
