Description Murray McAllister 2014-06-30 03:35:30 UTC 
A flaw was reported in D-Bus's file descriptor passing feature. A local attacker could use this flaw to cause an invalid file descriptor to be forwarded to a service or application, causing it to disconnect from the bus, typically resulting in that service or application exiting.

It is reported that versions 1.3.0 and newer are affected.

Acknowledgements:

Red Hat would like to thank D-Bus upstream for reporting this issue.
