WebKit in Apple iOS before 4 on the iPhone and iPod touch does not properly implement the history.replaceState method in certain situations involving IFRAME elements, which allows remote attackers to obtain sensitive information via a crafted HTML document.

Race condition in Passcode Lock in Apple iOS before 4 on the iPhone and iPod touch allows physically proximate attackers to bypass intended passcode requirements, and pair a locked device with a computer and access arbitrary data, via vectors involving the initial boot.

Use-after-free vulnerability in JavaScriptCore in WebKit in Apple iTunes before 9.2 on Windows, and Apple iOS before 4 on the iPhone and iPod touch, allows remote attackers to execute arbitrary code or cause a denial of service (application crash) via vectors related to page transitions, a different vulnerability than CVE-2010-1763 and CVE-2010-1769.

The HTTP client functionality in Apple iPhone OS 3.1 on the iPhone 2G and 3.1.3 on the iPhone 3GS allows remote attackers to cause a denial of service (Safari, Mail, or Springboard crash) via a crafted innerHTML property of a DIV element, related to a "malformed character" issue.

Safari on Apple iPhone OS 3.1.3 for iPod touch allows remote attackers to cause a denial of service (application crash) or possibly execute arbitrary code via a long string in a MARQUEE element.

Use-after-free vulnerability in WebKit in Apple Safari before 5.0 on Mac OS X 10.5 through 10.6 and Windows, Safari before 4.1 on Mac OS X 10.4, and Safari on Apple iPhone OS allows remote attackers to execute arbitrary code or cause a denial of service (application crash), or read the SMS database or other data, via vectors related to "attribute manipulation," as demonstrated by Vincenzo Iozzo and Ralf Philipp Weinmann during a Pwn2Own competition at CanSecWest 2010.
