Apple users aren't akin to restarting their systems too often, however Apple is suggesting they do it for the second time in as many days with a new security patch issued on Wednesday.

Following hot on the heels of the Safari 4.0.3 update issued on Tuesday, the 10.1MB Wednesday update promises to fix a loophole that lets a remote attacker "to cause the DNS server to unexpectedly terminate"

Right. If you know what that means, you're far geekier than us.

According to Apple's notes on the update "The issue affects servers which are masters for one or more zones, regardless of whether they accept updates. BIND is included with Mac OS X and Mac OS X Server but it is not enabled by default. This update addresses the issue by properly rejecting messages with a record of type 'ANY' where an assertion would previously have been raised."

Either way the company is recommending all users apply the update.
