Apple has released an update for Safari on both the Mac and Windows platforms. At the same time it has released updates for iOS and the Mac. These are security updates to close an exploit recently demonstrated at the PWN2OWN security challenge. It was Charlie Miller, a security researcher, who  successfully exploited iOS earlier this year by successfully hacking into an iPhone. Apple’s iOS also uses the WebKit rendering engine, which was exploited by VUPEN security in their 5 second attack on Mac OS X.

Here is what Apple says about the Safari update:

Note:

Certificates Trust Policy

Several fraudulent SSL certificates were issued by a Comodo affiliate registration authority. This may allow a man-in-the-middle attacker to redirect connections and intercept user credentials or other sensitive information. Safari relies on the certificate store of the host operating system to determine if an SSL server certificate is trustworthy. For Mac OS X systems, this issue is addressed with Security Update 2011-002. For iOS, this issue is addressed with iOS 4.3.2 and iOS 4.2.7. For Windows systems, applying the update described in Microsoft Knowledge Base Article 2524375 will cause Safari to regard these certificates as untrusted. The article is available athttp://support.microsoft.com/kb/2524375
