We've been talking on our show about these stolen/forged digital certificates that theoretically allow hackers to slip between your browser and a secure website and steal all your information. Most big tech companies have now blocked certificates coming from DigiNotar, the issuing authority that was hacked. Google has for Chrome, Microsoft has for IE, Mozilla has with Firefox. But Apple hasn't done anything about it and some people are getting worried and concerned.
Because Safari relies on the underlying operating system to tell it which certificates have been revoked or banned entirely, Apple must update Mac OS X. The Windows edition of Safari, which has a negligible share of the browser market, taps Windows' certificate list: That version is safe to use once Microsoft's Tuesday patch is applied.
