New upstream release fixes several security issues
- CVE-2014-3635: do not accept an extra fd in cmsg padding, avoiding a buffer overrun in dbus-daemon or system services - CVE-2014-3636: reduce maximum number of file descriptors per message from 1024 to 16, to avoid two separate denial-of-service attacks that could cause system services to be dropped from the bus - CVE-2014-3637: time out connections that have a partially-sent message containing a file descriptor, so that malicious processes cannot use self-referential file descriptors to make a connection that will never close - CVE-2014-3638: reduce maximum number of pending replies per connection to avoid algorithmic complexity DoS - CVE-2014-3639: reduce timeout for authentication and do not accept() new connections when all unauthenticated connection slots are in use, so that malicious processes cannot prevent new connections to the system bus
