The Passcode Lock implementation in Apple iOS before 6 allows physically proximate attackers to bypass an intended passcode requirement via vectors related to ending a FaceTime call.

The Sorenson codec in QuickTime in Apple Mac OS X before 10.7.5, and in CoreMedia in iOS before 6, accesses uninitialized memory locations, which allows remote attackers to execute arbitrary code or cause a denial of service (application crash) via a crafted movie file with Sorenson encoding.

The Passcode Lock implementation in Apple iOS before 6 allows physically proximate attackers to bypass an intended passcode requirement via vectors involving use of the camera.

Buffer overflow in the IPsec component in Apple iOS before 6 allows remote attackers to execute arbitrary code via a crafted racoon configuration file.

The DNAv4 protocol implementation in the DHCP component in Apple iOS before 6 sends Wi-Fi packets containing a MAC address of a host on a previously used network, which might allow remote attackers to obtain sensitive information about previous device locations by sniffing an unencrypted Wi-Fi network for these packets.

UIWebView in UIKit in Apple iOS before 6 does not properly use the Data Protection feature, which allows context-dependent attackers to obtain cleartext file content by leveraging direct access to a device's filesystem.

Messages in Apple iOS before 6, when multiple iMessage e-mail addresses are configured, does not ensure that a reply's sender address matches the recipient address of the original message, which allows remote attackers to obtain potentially sensitive information about alternate e-mail addresses in opportunistic circumstances by reading a reply.

Mail in Apple iOS before 6 does not properly handle reuse of Content-ID header values, which allows remote attackers to spoof attachments via a header value that was also used in a previous e-mail message, as demonstrated by a message from a different sender.

The Passcode Lock implementation in Apple iOS before 6 does not properly restrict photo viewing, which allows physically proximate attackers to view arbitrary stored photos by spoofing a time value.

WebKit, as used in Apple iOS before 6, allows remote attackers to execute arbitrary code or cause a denial of service (memory corruption and application crash) via a crafted web site.
