The JavaScript implementation in WebKit in Apple Safari before 5.0.3 on Mac OS X 10.5 through 10.6 and Windows, and before 4.1.3 on Mac OS X 10.4, uses a weak algorithm for generating values of random numbers, which makes it easier for remote attackers to track a user by predicting a value, a related issue to CVE-2008-5913 and CVE-2010-3171.

Integer overflow in WebKit in Apple Safari before 5.0.3 on Mac OS X 10.5 through 10.6 and Windows, and before 4.1.3 on Mac OS X 10.4, allows remote attackers to execute arbitrary code or cause a denial of service (application crash) via a crafted string.

Integer overflow in the Text::wholeText method in dom/Text.cpp in WebKit, as used in Apple Safari before 5.0.3 on Mac OS X 10.5 through 10.6 and Windows, and before 4.1.3 on Mac OS X 10.4; webkitgtk before 1.2.6; and possibly other products allows remote attackers to execute arbitrary code or cause a denial of service (application crash) via vectors involving Text objects.

Use-after-free vulnerability in WebKit in Apple Safari before 5.0.3 on Mac OS X 10.5 through 10.6 and Windows, and before 4.1.3 on Mac OS X 10.4, allows remote attackers to execute arbitrary code or cause a denial of service (application crash) via vectors involving inline text boxes.

WebKit in Apple Safari before 5.0.3 on Mac OS X 10.5 through 10.6 and Windows, and before 4.1.3 on Mac OS X 10.4, does not properly perform a cast of an unspecified variable during processing of Cascading Style Sheets (CSS) 3D transforms, which allows remote attackers to execute arbitrary code or cause a denial of service (application crash) via a crafted web site.

Use-after-free vulnerability in WebKit in Apple Safari before 5.0 on Mac OS X 10.5 through 10.6 and Windows, Safari before 4.1 on Mac OS X 10.4, and Safari on Apple iPhone OS allows remote attackers to execute arbitrary code or cause a denial of service (application crash), or read the SMS database or other data, via vectors related to "attribute manipulation," as demonstrated by Vincenzo Iozzo and Ralf Philipp Weinmann during a Pwn2Own competition at CanSecWest 2010.

Multiple unspecified vulnerabilities in WebKit in Apple Safari before 4.0.4 on Windows allow remote FTP servers to execute arbitrary code, cause a denial of service (application crash), or obtain sensitive information via a crafted directory listing in a reply.

The HTMLMediaElement::loadResource function in html/HTMLMediaElement.cpp in WebCore in WebKit before r49480, as used in Apple Safari before 4.0.4 on Mac OS X, does not perform the expected callbacks for HTML 5 media elements that have external URLs for media resources, which allows remote attackers to trigger sub-resource requests to arbitrary web sites via a crafted HTML document, as demonstrated by an HTML e-mail message that uses a media element for X-Confirm-Reading-To functionality, aka rdar problem 7271202.

Apple Safari before 4.0.4 does not properly implement certain (1) Open Image and (2) Open Link menu options, which allows remote attackers to read local HTML files via a crafted web site.

Apple Safari, possibly before 4.0.3, on Mac OS X does not properly handle a '\0' character in a domain name in the subject's Common Name (CN) field of an X.509 certificate, which allows man-in-the-middle attackers to spoof arbitrary SSL servers via a crafted certificate issued by a legitimate Certification Authority, a related issue to CVE-2009-2408.
