Apple Safari 4.0_beta

Buffer overflow in WebKit in Apple Safari before 4.0.3 allows remote attackers to execute arbitrary code or cause a denial of service (application crash) via crafted floating-point numbers.

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.

WebKit in Apple Safari before 4.0.3 does not properly restrict the URL scheme of the pluginspage attribute of an EMBED element, which allows user-assisted remote attackers to launch arbitrary file: URLs and obtain sensitive information via a crafted HTML document.
