Use-after-free vulnerability in the JavaScript DOM implementation in WebKit in Apple Safari before 4.0, iPhone OS 1.0 through 2.2.1, and iPhone OS for iPod touch 1.1 through 2.2.1 allows remote attackers to execute arbitrary code or cause a denial of service (application crash) by destroying a document.body element that has an unspecified XML container with elements that support the dir attribute.

The XSLT implementation in WebKit in Apple Safari before 4.0, iPhone OS 1.0 through 2.2.1, and iPhone OS for iPod touch 1.1 through 2.2.1 does not properly handle redirects, which allows remote attackers to read XML content from arbitrary web pages via a crafted document.

WebKit in Apple Safari before 4.0, iPhone OS 1.0 through 2.2.1, and iPhone OS for iPod touch 1.1 through 2.2.1 does not initialize a pointer during handling of a Cascading Style Sheets (CSS) attr function call with a large numerical argument, which allows remote attackers to execute arbitrary code or cause a denial of service (memory corruption and application crash) via a crafted HTML document.

Safari in Apple iPhone OS 1.0 through 2.1 and iPhone OS for iPod touch 1.1 through 2.1 does not isolate the call-approval dialog from the process of launching new applications, which allows remote attackers to make arbitrary phone calls via a crafted HTML document.

Safari in Apple iPhone OS 2.0 through 2.1 and iPhone OS for iPod touch 2.1 through 2.1 does not restrict an IFRAME's content display to the boundaries of the IFRAME, which allows remote attackers to spoof a user interface via a crafted HTML document.

Safari in Apple iPhone OS 1.0 through 2.1 and iPhone OS for iPod touch 1.1 through 2.1 does not properly handle HTML TABLE elements, which allows remote attackers to execute arbitrary code or cause a denial of service (memory corruption and application crash) via a crafted HTML document.

The Passcode Lock feature in Apple iPhone OS 1.0 through 2.1 and iPhone OS for iPod touch 1.1 through 2.1 displays SMS messages when the emergency-call screen is visible, which allows physically proximate attackers to obtain sensitive information by reading these messages. NOTE: this might be a duplicate of CVE-2008-4593.

Race condition in the Passcode Lock feature in Apple iPhone OS 2.0 through 2.1 and iPhone OS for iPod touch 2.0 through 2.1 allows physically proximate attackers to remove the lock and launch arbitrary applications by restoring the device from a backup.

The Passcode Lock feature in Apple iPhone OS 1.0 through 2.1 and iPhone OS for iPod touch 1.1 through 2.1 allows physically proximate attackers to leverage the emergency-call ability of locked devices to make a phone call to an arbitrary number.

Apple iPhone OS 1.0 through 2.1 and iPhone OS for iPod touch 1.1 through 2.1 changes the encryption level of PPTP VPN connections to a lower level than was previously used, which makes it easier for remote attackers to obtain sensitive information or hijack a connection by decrypting network traffic.

ImageIO in Apple iPhone OS 1.0 through 2.1 and iPhone OS for iPod touch 1.1 through 2.1 allow remote attackers to cause a denial of service (memory consumption and device reset) via a crafted TIFF image.
