Ironically, a fairly simple exploit can be used to bypass the lockscreen on iOS 7 and gain access to photos already, but the bugs fixed in iOS 7 are, in cases, very serious. Some could be used as part of DOS attacks on devices, or even be used to execute arbitrary code which could potentially leave a device open to being taken over.
One flaw (CVE-2013-0957) could allow an attacker to break an app in the third party Sandbox and determine the user's passcode.
The update also fixed a widely reported flaw that allowed a modified charger to be used to hijack a device. Other bugs included s Safari bug that made previously-deleted history visible again and a memory corruption issue related to the handling of XML by the Apple browser.
