Description Murray McAllister 2014-09-11 04:06:49 EDT
A denial of service flaw was reported in the way D-Bus handled incomplete connections. By repeatedly making incomplete connections, a local, malicious user could prevent new connections to the bus.

It was reported that all versions of D-Bus are affected.

Acknowledgements:

Red Hat would like to thank D-Bus upstream for reporting this issue. Upstream acknowledges Alban Crequy as the original reporter.
