Apple iPhone OS 4.3.1

The history-clearing feature in Safari in Apple iOS before 7 does not clear the back/forward history of an open tab, which allows physically proximate attackers to obtain sensitive information by leveraging an unattended workstation.

The Restrictions (aka Parental Controls) implementation in Apple iOS before 6 does not properly handle purchase attempts after a Disable Restrictions action, which allows local users to bypass an intended Apple ID authentication step via an app that performs purchase transactions.

lockdownd in Lockdown in Apple iOS before 6.1.3 does not properly consider file types during the permission-setting step of a backup restoration, which allows local users to change the permissions of arbitrary files via a backup that contains a pathname with a symlink.

The Berkeley Packet Filter (BPF) interpreter implementation in the kernel in Apple iOS before 6 accesses uninitialized memory locations, which allows local users to obtain sensitive information about the layout of kernel memory via a crafted program that uses a BPF interface.

Office Viewer in Apple iOS before 6 writes cleartext document data to a temporary file, which might allow local users to bypass a document's intended (1) Data Protection level or (2) encryption state by reading the temporary content.

The Passcode Lock feature in Apple iOS before 5.0.1 on the iPad 2 does not properly implement the locked state, which allows physically proximate attackers to access data by opening a Smart Cover during power-off confirmation.
