Apple Inc. issued a security patch that will eliminate DNS fault and fix Apple's implementation of the Berkeley Internet Name Domain (BIND) DNS server in Mac OS X v10.4.11, Mac OS X Server v10.4.11, Mac OS X v10.5.4, and Mac OS X Server v10.5.4.

The DNS fault allow an attacker to execute a cache poisoning attack and as a result the user can type in the correct name for a Web site, but get a fake website on the system instead. This mismatch could enhance the chances of phishing attack and it could be a time killing and mystifying job for a user.

With the use of patch, the traffic on the domain can be redirected after malicious content entry. There are some vendors like Microsoft and Cisco in the market which have their own patches to deal with such a radical situation.

Some network administrators have reported compatibility problems with early patches. But, Apple's novel patch eliminated this problem. A user can download the patch from company's official website.
