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.

Integer overflow in ColorSync in Apple Mac OS X 10.4.11 and 10.5.8, and Safari before 4.0.4 on Windows, allows remote attackers to execute arbitrary code or cause a denial of service (application crash) via a crafted ColorSync profile embedded in an image, leading to a heap-based buffer overflow.

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.

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.

Incomplete blacklist vulnerability in WebKit in Apple Safari before 4.0.3, as used on iPhone OS before 3.1, iPhone OS before 3.1.1 for iPod touch, and other platforms, allows remote attackers to spoof domain names in URLs, and possibly conduct phishing attacks, via unspecified homoglyphs.

Multiple use-after-free vulnerabilities in libxml2 2.5.10, 2.6.16, 2.6.26, 2.6.27, and 2.6.32, and libxml 1.8.17, allow context-dependent attackers to cause a denial of service (application crash) via crafted (1) Notation or (2) Enumeration attribute types in an XML file, as demonstrated by the Codenomicon XML fuzzing framework.

WebKit in Apple Safari before 4.0.2, as used on iPhone OS before 3.1, iPhone OS before 3.1.1 for iPod touch, and other platforms; KHTML in kdelibs in KDE; QtWebKit (aka Qt toolkit); and possibly other products do not properly handle numeric character references, which allows remote attackers to execute arbitrary code or cause a denial of service (memory corruption and application crash) via a crafted HTML document.
