The Cascading Style Sheets (CSS) implementation in WebKit in Apple Safari before 5.0 on Mac OS X 10.5 through 10.6 and Windows, and before 4.1 on Mac OS X 10.4, allows remote attackers to discover sensitive URLs via an HREF attribute associated with a redirecting URL.

Use-after-free vulnerability in WebKit in Apple Safari before 5.0 on Mac OS X 10.5 through 10.6 and Windows, and before 4.1 on Mac OS X 10.4, allows remote attackers to execute arbitrary code or cause a denial of service (application crash) via vectors related to HTML buttons and the first-letter CSS style.

Multiple directory traversal vulnerabilities in the (a) Local Storage and (b) Web SQL database implementations in WebKit in Apple Safari before 5.0 on Mac OS X 10.5 through 10.6 and Windows, and before 4.1 on Mac OS X 10.4, allow remote attackers to create arbitrary database files via vectors involving a (1) %2f and .. (dot dot) or (2) %5c and .. (dot dot) in a URL.

Cross-site scripting (XSS) vulnerability in WebKit in Apple Safari before 5.0 on Mac OS X 10.5 through 10.6 and Windows, and before 4.1 on Mac OS X 10.4, allows remote attackers to inject arbitrary web script or HTML via vectors related to improper UTF-7 canonicalization, and lack of termination of a quoted string in an HTML document.

Cross-site scripting (XSS) vulnerability in WebKit in Apple Safari before 5.0 on Mac OS X 10.5 through 10.6 and Windows, and before 4.1 on Mac OS X 10.4, allows user-assisted remote attackers to inject arbitrary web script or HTML via vectors involving a (1) paste or (2) drag-and-drop operation for a selection.

WebKit in Apple Safari before 5.0 on Mac OS X 10.5 through 10.6, and before 4.1 on Mac OS X 10.4, does not properly handle clipboard (1) drag and (2) paste operations for URLs, which allows user-assisted remote attackers to read arbitrary files via a crafted HTML document.

WebKit.dll in WebKit, as used in Safari.exe 4.531.9.1 in Apple Safari, allows remote attackers to cause a denial of service (application crash) via JavaScript that writes <marquee> sequences in an infinite loop.

The JavaScript implementation in WebKit allows remote attackers to send selected keystrokes to a form field in a hidden frame, instead of the intended form field in a visible frame, via certain calls to the focus method.

The image decoder in WebKit before r52833, as used in Google Chrome before 4.0.249.78, does not properly handle a failure of memory allocation, which allows remote attackers to execute arbitrary code in the Chrome sandbox via a malformed GIF file that specifies a large size.

WebKit before r51295, as used in Google Chrome before 4.0.249.78, presents a directory-listing page in response to an XMLHttpRequest for a file:/// URL that corresponds to a directory, which allows attackers to obtain sensitive information or possibly have unspecified other impact via a crafted local HTML document.

WebKit before r52784, as used in Google Chrome before 4.0.249.78 and Apple Safari before 4.0.5, permits cross-origin loading of CSS stylesheets even when the stylesheet download has an incorrect MIME type and the stylesheet document is malformed, which allows remote attackers to obtain sensitive information via a crafted document.

WebKit before r53525, as used in Google Chrome before 4.0.249.89, allows remote attackers to execute arbitrary code in the Chrome sandbox via a malformed RUBY element, as demonstrated by a <ruby>><table><rt> sequence.

Cross-site scripting (XSS) vulnerability in Apple WebKit, as used in Safari before 3.1.1, allows remote attackers to inject arbitrary web script or HTML via a crafted URL with a colon in the hostname portion.

Multiple heap-based buffer overflows in the Perl Compatible Regular Expressions (PCRE) library in the JavaScript engine in WebKit in Apple Safari 3 Beta before Update 3.0.3, and iPhone before 1.0.1, allow remote attackers to execute arbitrary code via certain JavaScript regular expressions. NOTE: this issue was originally reported only for MobileSafari on the iPhone. NOTE: it is not clear whether this stems from an issue in the original distribution of PCRE, which might already have a separate CVE identifier.
