The FT_Stream_EnterFrame function in base/ftstream.c in FreeType before 2.4.2 does not properly validate certain position values, which allows remote attackers to cause a denial of service (application crash) or possibly execute arbitrary code via a crafted font file.

Multiple stack-based buffer overflows in the cff_decoder_parse_charstrings function in the CFF Type2 CharStrings interpreter in cff/cffgload.c in FreeType before 2.4.2, as used in Apple iOS before 4.0.2 on the iPhone and iPod touch and before 3.2.2 on the iPad, allow remote attackers to execute arbitrary code or cause a denial of service (memory corruption) via crafted CFF opcodes in embedded fonts in a PDF document, as demonstrated by JailbreakMe. NOTE: some of these details are obtained from third party information.

Integer overflow in IOSurface in Apple iOS before 4.0.2 on the iPhone and iPod touch, and before 3.2.2 on the iPad, allows local users to gain privileges via vectors involving IOSurface properties, as demonstrated by JailbreakMe.

The Citibank Citi Mobile app before 2.0.3 for iOS stores account data in a file, which allows local users to obtain sensitive information via vectors involving (1) the mobile device or (2) a synchronized computer.

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.

WebKit in Apple iOS before 4 on the iPhone and iPod touch does not enforce the expected boundary restrictions on content display by an IFRAME element, which allows remote attackers to spoof the user interface via a crafted HTML document.

The Settings application in Apple iOS before 4 on the iPhone and iPod touch does not properly report the wireless network that is in use, which might make it easier for remote attackers to trick users into communicating over an unintended network.

Safari in Apple iOS before 4 on the iPhone and iPod touch does not properly implement the Accept Cookies preference, which makes it easier for remote web servers to track users via a cookie.

Passcode Lock in Apple iOS before 4 on the iPhone and iPod touch does not properly handle alert-based unlocks in conjunction with subsequent Remote Lock operations through MobileMe, which allows physically proximate attackers to bypass intended passcode requirements via unspecified vectors.

ImageIO in Apple iOS before 4 on the iPhone and iPod touch allows remote attackers to execute arbitrary code or cause a denial of service (memory corruption and application crash) via a crafted JPEG image.

Stack-based buffer overflow in CFNetwork in 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 URL handling.

Application Sandbox in Apple iOS before 4 on the iPhone and iPod touch does not prevent photo-library access, which might allow remote attackers to obtain location information via unspecified vectors.

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.

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.

Stack consumption vulnerability in the WebCore::CSSSelector function in WebKit, as used in Apple Safari 4.0.4, Apple Safari on iPhone OS and iPhone OS for iPod touch, and Google Chrome 4.0.249, allows remote attackers to cause a denial of service (application crash) or possibly execute arbitrary code via a STYLE element composed of a large number of *> sequences.

Recovery Mode in Apple iPhone OS 1.0 through 3.1.2, and iPhone OS for iPod touch 1.1 through 3.1.2, allows physically proximate attackers to bypass device locking, and read or modify arbitrary data, via a USB control message that triggers memory corruption.

The implementation of Cross-Origin Resource Sharing (CORS) in WebKit, as used in Apple Safari before 4.0.4 and Google Chrome before 3.0.195.33, includes certain custom HTTP headers in the OPTIONS request during cross-origin operations with preflight, which makes it easier for remote attackers to conduct cross-site request forgery (CSRF) attacks via a crafted web page.

iPhone Mail in Apple iPhone OS, and iPhone OS for iPod touch, does not validate X.509 certificates, which allows man-in-the-middle attackers to spoof arbitrary SSL e-mail servers via a crafted certificate.

The Telephony component in Apple iPhone OS before 3.1 does not properly handle SMS arrival notifications, which allows remote attackers to cause a denial of service (NULL pointer dereference and service interruption) via a crafted SMS message.

The WebKit component in Safari in Apple iPhone OS before 3.1, and iPhone OS before 3.1.1 for iPod touch, does not remove usernames and passwords from URLs sent in Referer headers, which allows remote attackers to obtain sensitive information by reading Referer logs on a web server.
