Apple silently rolled out an update to its mobile operating system to resolve the SSL encryption vulnerability.

Apple continues to address the ongoing issues with its controversial update, iOS7, by releasing fixes more frequently. The latest one arrives just three weeks after the iOS 7.0.5, which was for a minor bug causing network errors on iPhone 5S and iPhone 5C in China. The Cupertino tech giant fixed an SSL or Secure Sockets Layer encryption vulnerability, which is regarded as one of the most basic type of encryption for online activities.

The over-the-air update, which arrived Friday, prevents an unauthorized person from capturing and modifying data. The SSL encountered some issues about the authenticity of the connection and the latest update fixes that by adding the missing steps required in the validation process, the company said in an update description page.

The patch is available for older versions of Apple's mobile operating systems in iOS 6.1.6 for iPhone 3GS and fourth-generation iPod Touch, devices that do not support iOS7.

Apple is expected to announce its next biggest update, iOS 7.1 next month. Reports have it that the upcoming OS version has already hit beta testing. The update will bring a slew of changes to iOS 7 including natural-sounding updates to Siri's Australian English, U.K. English, Japanese and Mandarin Chinese voices, according to iOS 7.1 beta 5 download notes. Other features include addition of Shift and Caps lock key on the keyboard, new wallpaper option, tweaked Calendar app, speed improvements and new version of Apple TV beta software, reports MacRumors.

Apple's iOS 7.1 is likely to feature the changes already spotted in all its five betas. A separate report from Design Trend hints at a possible integration of iOS in the car feature, which will let users talk to Siri, get directions, play music, reply to text messages and more.
