Apple Safari does not require a cached certificate before displaying a lock icon for an https web site, which allows man-in-the-middle attackers to spoof an arbitrary https site by sending the browser a crafted (1) 4xx or (2) 5xx CONNECT response page for an https request sent through a proxy server.

Apple Safari before 3.2.2 processes a 3xx HTTP CONNECT response before a successful SSL handshake, which allows man-in-the-middle attackers to execute arbitrary web script, in an https site's context, by modifying this CONNECT response to specify a 302 redirect to an arbitrary https web site.

Apple Safari detects http content in https web pages only when the top-level frame uses https, which allows man-in-the-middle attackers to execute arbitrary web script, in an https site's context, by modifying an http page to include an https iframe that references a script file on an http site, related to "HTTP-Intended-but-HTTPS-Loadable (HPIHSL) pages."

The Installer in Apple Safari before 4.0 on Windows allows local users to gain privileges by checking a box that specifies an immediate launch of the application after installation, related to an unspecified compression method.

Cross-site scripting (XSS) vulnerability in Web Inspector in WebKit in Apple Safari before 4.0 allows user-assisted remote attackers to inject arbitrary web script or HTML, and read local files, via vectors related to the improper escaping of HTML attributes.

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.

CFNetwork in Apple Safari before 4.0 on Windows does not properly protect the temporary files created for downloads, which allows local users to obtain sensitive information by reading these files.

Use-after-free vulnerability in the garbage-collection implementation in WebCore in WebKit in Apple Safari before 4.0 allows remote attackers to execute arbitrary code or cause a denial of service (heap corruption and application crash) via an SVG animation element, related to SVG set objects, SVG marker elements, the targetElement attribute, and unspecified "caches."

The XSLT functionality in WebKit in Apple Safari before 4.0 does not properly implement the document function, which allows remote attackers to read (1) arbitrary local files and (2) files from different security zones via unspecified vectors.

CRLF injection 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 HTTP headers and bypass the Same Origin Policy via a crafted HTML document, related to cross-site scripting (XSS) attacks that depend on communication with arbitrary web sites on the same server through use of XMLHttpRequest without a Host header.
