This patch affects users of Windows Vista, XP SP2, SP3, 2003, and 2000. The update addresses the vulnerability detailed within CVE-2008-3635. Apple explains that "Bonjour for Windows provides Zero Configuration Networking, Multicast DNS, and Network Service Discovery for Windows users. It's also possible to use the Bonjour API to issue conventional unicast DNS queries. A weakness in the DNS protocol may allow a remote attacker to spoof DNS responses. As a result, if there are applications that use Bonjour for Windows for unicast DNS, those applications may receive forged information. However, there are no known applications that use the Bonjour APIs for unicast DNS hostname resolution." This issue does not affect systems running Mac OS X.
