WebKit in Apple Safari before 4.0 allows remote attackers to spoof the browser's display of (1) the host name, (2) security indicators, and unspecified other UI elements via a custom cursor in conjunction with a modified CSS3 hotspot property.

WebKit in Apple Safari before 4.0 does not prevent references to file: URLs within (1) audio and (2) video elements, which allows remote attackers to determine the existence of arbitrary files via a crafted HTML document.

Cross-site scripting (XSS) vulnerability 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 inject arbitrary web script or HTML via vectors related to improper handling of Location and History objects.

CFNetwork in Apple Safari before 4.0 misinterprets downloaded image files as local HTML documents in unspecified circumstances, which allows remote attackers to execute arbitrary JavaScript code by placing it in an image file.

WebKit in Apple Safari before 4.0 does not prevent remote loading of local Java applets, which allows remote attackers to execute arbitrary code, gain privileges, or obtain sensitive information via an APPLET or OBJECT element.

Apple Safari before 4.0 does not prevent calls to the open-help-anchor URL handler by web sites, which allows remote attackers to open arbitrary local help files, and execute arbitrary code or obtain sensitive information, via a crafted call.

WebKit in Apple Safari before 4.0 does not properly initialize memory for Attr DOM objects, which allows remote attackers to execute arbitrary code or cause a denial of service (application crash) via a crafted HTML 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 uses predictable random numbers in JavaScript applications, which makes it easier for remote web servers to track the behavior of a Safari user during a session.

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.
