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.

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 HTML elements with right-to-left (RTL) text directionality.

WebKit in Apple Safari before 4.0.5 does not properly validate the cross-origin loading of stylesheets, which allows remote attackers to obtain sensitive information via a crafted HTML document. NOTE: this might overlap CVE-2010-0651.

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 vectors related to the run-in Cascading Style Sheets (CSS) display property.

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 vectors related to "callbacks for HTML elements."

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 vectors involving HTML IMG elements.

Apple Safari before 4.0.5 on Windows does not properly validate external URL schemes, which allows remote attackers to open local files and execute arbitrary code via a crafted HTML document.

PubSub in Apple Safari before 4.0.5 does not properly implement use of the Accept Cookies preference to block cookies, which makes it easier for remote web servers to track users by setting a cookie in a (1) RSS or (2) Atom feed.

The Cascading Style Sheets (CSS) implementation in WebKit in Apple Safari before 4.0.5 allows remote attackers to execute arbitrary code or cause a denial of service (memory corruption and application crash) via crafted format arguments.

ImageIO in Apple Safari before 4.0.5 and iTunes before 9.1 on Windows does not ensure that memory access is associated with initialized memory, which allows remote attackers to obtain potentially sensitive information from process memory via a crafted TIFF image.
