Off-by-one error in the webdrawInRect:withFont:ellipsis:alignment:measureOnly function in WebKit in Safari in Apple iPhone 1.1.4 and 2.0 and iPod touch 1.1.4 and 2.0 allows remote attackers to cause a denial of service (browser crash) via a JavaScript alert call with an argument that lacks breakable characters and has a length that is a multiple of the memory page size, leading to an out-of-bounds read.

Safari on Apple iPhone before 2.0 and iPod touch before 2.0 misinterprets a menu button press as user confirmation for visiting a web site with a (1) self-signed or (2) invalid certificate, which makes it easier for remote attackers to spoof web sites.

JavaScriptCore in WebKit on Apple iPhone before 2.0 and iPod touch before 2.0 does not properly perform runtime garbage collection, which allows remote attackers to execute arbitrary code or cause a denial of service (application crash) via unspecified vectors that trigger memory corruption, a different vulnerability than CVE-2008-2317.

Safari on Apple iPhone before 2.0 and iPod touch before 2.0 allows remote attackers to spoof the address bar via Unicode ideographic spaces in the URL.
