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.

Konqueror Embedded and KDE 2.2.2 and earlier does not validate the Common Name (CN) field for X.509 Certificates, which could allow remote attackers to spoof certificates via a man-in-the-middle attack.

Apple Safari before 5.0.6 allows remote attackers to bypass the Same Origin Policy, and modify the rendering of text from arbitrary web sites, via a Java applet that loads fonts.

CFNetwork in Apple Safari before 5.0.6 on Windows does not properly handle an untrusted attribute of a system root certificate, which allows remote web servers to bypass intended SSL restrictions via a certificate signed by a blacklisted certification authority.

Cross-site scripting (XSS) vulnerability in Safari before 3.2.3, and 4 Public Beta, on Apple Mac OS X 10.5 before 10.5.7 and Windows allows remote attackers to inject arbitrary web script or HTML via a crafted feed: URL.
