iOS 7.0.6 and iOS 6.1.6
Apple releases iOS 7.0.6 and iOS 6.1.6 through Software Update.
This security update provides a fix for SSL connection verification.
Available for: iPhone 4 and later, iPod touch (5th generation), iPad 2 and later
Impact: An attacker with a privileged network position may capture or modify data in sessions protected by SSL/TLS
Description: Secure Transport failed to validate the authenticity of the connection. This issue was addressed by restoring missing validation steps.
It is unclear if this issue has been fixed in recent iOS 7.1 beta build. According to a well connected iOS Developer, Apple would release iOS 7.1 GM build in the coming weeks.
