Description Murray McAllister 2014-09-11 08:01:33 UTC 
A denial of service flaw was reported in D-Bus's method call handling. A local, malicious user could open a large number of parallel connections that all send the maximum number of method calls, causing subsequent calls to slow considerably.

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.
