Buffer overflow in OfficeImport in Apple iOS before 5 allows remote attackers to execute arbitrary code or cause a denial of service (application crash) via a crafted Microsoft Word document.

The Settings component in Apple iOS before 5, when a configuration profile is used for a locale other than English, does not properly implement localization, which makes it easier for attackers to have an unspecified impact by leveraging incorrect configuration display.

The Data Access component in Apple iOS before 5 does not properly handle the existence of multiple user accounts on the same mail server, which allows local users to bypass intended access restrictions in opportunistic circumstances by leveraging a different account's cookie.

The Data Security component in Apple iOS before 4.2.10 and 4.3.x before 4.3.5 does not check the basicConstraints parameter during validation of X.509 certificate chains, which allows man-in-the-middle attackers to spoof an SSL server by using a non-CA certificate to sign a certificate for an arbitrary domain.

The queueing primitives in IOMobileFrameBuffer in Apple iOS before 4.2.9 and 4.3.x before 4.3.4 do not properly perform type conversion, which allows local users to gain privileges via a crafted application.

Integer signedness error in psaux/t1decode.c in FreeType before 2.4.6, as used in CoreGraphics in Apple iOS before 4.2.9 and 4.3.x before 4.3.4 and other products, allows remote attackers to execute arbitrary code or cause a denial of service (memory corruption and application crash) via a crafted Type 1 font in a PDF document, as exploited in the wild in July 2011.

MobileSafari in Apple iOS before 4.3 does not properly implement application launching through URL handlers, which allows remote attackers to cause a denial of service (persistent application crash) via crafted JavaScript code.

WebKit, as used in Apple Safari before 5.0.4 and iOS before 4.3, does not properly handle unspecified "cached resources," which allows remote attackers to cause a denial of service (resource unavailability) via a crafted web site that conducts a cache-poisoning attack.

Wi-Fi in Apple iOS before 4.3 and Apple TV before 4.2 does not properly perform bounds checking for Wi-Fi frames, which allows remote attackers to cause a denial of service (device reset) via unspecified traffic on the local wireless network.

WebKit, as used in Apple Safari before 5.0.4 and iOS before 4.3, does not properly handle the Attr.style accessor, which allows remote attackers to bypass the Same Origin Policy and inject Cascading Style Sheets (CSS) token sequences via a crafted web site.
