Two vulnerabilities have been identified in Apple Bonjour for Windows, which could be exploited by attackers to cause a denial of service or spoof DNS responses.
The first issue is caused by a NULL pointer dereference error in the Bonjour Namespace Provider when resolving a specially crafted ".local" domain name containing a long DNS label, which could be exploited to crash an affected application.
The second vulnerability is caused by an error in the DNS protocol, which may allow a remote attacker to spoof DNS responses.
