Use-after-free vulnerability in WebKit in Apple Safari before 5.0 on Mac OS X 10.5 through 10.6 and Windows, and before 4.1 on Mac OS X 10.4, allows remote attackers to execute arbitrary code or cause a denial of service (application crash) via vectors related to the Cascading Style Sheets (CSS) run-in property and multiple invocations of a destructor for a child element that has been referenced multiple times.

The Cascading Style Sheets (CSS) implementation in WebKit in Apple Safari before 5.0 on Mac OS X 10.5 through 10.6 and Windows, and before 4.1 on Mac OS X 10.4, allows remote attackers to execute arbitrary code or cause a denial of service (memory corruption and application crash) via HTML content that contains multiple :after pseudo-selectors.

WebKit in Apple Safari before 5.0 on Mac OS X 10.5 through 10.6 and Windows, and before 4.1 on Mac OS X 10.4, allows remote attackers to execute arbitrary code or cause a denial of service (memory corruption and application crash) via an SVG document with nested use elements.

Use-after-free vulnerability in WebKit in Apple Safari before 5.0 on Mac OS X 10.5 through 10.6 and Windows, and before 4.1 on Mac OS X 10.4, allows remote attackers to execute arbitrary code or cause a denial of service (application crash) via vectors related to HTML buttons and the first-letter CSS style.

WebKit in Apple Safari before 5.0 on Mac OS X 10.5 through 10.6 and Windows, and before 4.1 on Mac OS X 10.4, sends an https URL in the Referer header of an http request in certain circumstances involving https to http redirection, which allows remote HTTP servers to obtain potentially sensitive information via standard HTTP logging, a related issue to CVE-2010-0660.

WebKit in Apple Safari before 5.0 on Mac OS X 10.5 through 10.6 and Windows, and before 4.1 on Mac OS X 10.4, allows remote attackers to bypass intended restrictions on outbound connections to "non-default TCP ports" via a crafted port number, related to an "integer truncation issue." NOTE: this may overlap CVE-2010-1099.

WebKit in Apple Safari before 5.0 on Mac OS X 10.5 through 10.6 and Windows, and before 4.1 on Mac OS X 10.4, does not properly restrict the reading of a canvas that contains an SVG image pattern from a different web site, which allows remote attackers to read images from other sites via a crafted canvas, related to a "cross-site image capture issue."

Apple Safari before 5.0 on Mac OS X 10.5 through 10.6 and Windows, and before 4.1 on Mac OS X 10.4, does not provide a warning about a (1) http or (2) https URL that contains a username and password, which makes it easier for remote attackers to conduct phishing attacks via a crafted URL.
