Apple security researchers revealed last week that the latest iOS update had a coding error that bypassed a key validation step during SSL encryption and requires an iOS Patch. This meant that communications sent over unsecured Wi-Fi hot spots could have been intercepted and read while unencrypted, potentially exposing user password, bank data and other sensitive information. Secured Wi-Fi networks (e.g. home and business networks) with encryption enabled are not affected.
On Saturday, several security researches reported that the flaw also affected OS X 10.9 and other OS X versions. On OS X, the SSL security issue is limited to unsecured Wi-Fi networks, but only through Safari. unfortunately for the iOS platform, it uses the WebKit based Safari engine even in non-Safari browsers. This means all iOS browsers can be exploited.
Apple has reported that they have already fixed the OS X issue and will be releasing an iOS Patch for the iOS platform soon too.
