Two vulnerabilities have been reported in Apple Bonjour for Windows, which can be exploited by malicious people to cause a DoS (Denial of Service) or spoof DNS responses.

1) A NULL pointer dereference error in the Bonjour Namespace Provider component when resolving ".local" domain names can be exploited to cause a crash the application via a specially crafted ".local" domain name containing an overly long DNS label.

2) An error in the Bonjour API due to lack of randomization when issuing unicast DNS queries can be exploited to spoof DNS responses.
