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.

Use-after-free vulnerability in WebKit in Apple Safari before 4.0.5 allows remote attackers to execute arbitrary code or cause a denial of service (application crash) via an HTML document with improperly nested tags.

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.

Multiple use-after-free vulnerabilities in libxml2 2.5.10, 2.6.16, 2.6.26, 2.6.27, and 2.6.32, and libxml 1.8.17, allow context-dependent attackers to cause a denial of service (application crash) via crafted (1) Notation or (2) Enumeration attribute types in an XML file, as demonstrated by the Codenomicon XML fuzzing framework.
