The updated packages fix a security vulnerability: An issue was discovered in dbus >= 1.3.0 before 1.12.18
Summary
The updated packages fix a security vulnerability:
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 attacker with
access to the D-Bus system bus or another system service's private
AF_UNIX socket could use this to make the system service reach its file
descriptor limit, denying service to subsequent D-Bus clients.
(CVE-2020-12049)
