Multiple use-after-free vulnerabilities in WebKit in Apple Safari before 5.0.1 on Mac OS X 10.5 through 10.6 and Windows, and before 4.1.1 on Mac OS X 10.4; and webkitgtk before 1.2.6; allow remote attackers to execute arbitrary code or cause a denial of service (application crash) via a (1) font-face or (2) use element in an SVG document.

WebKit in Apple Safari before 5.0.1 on Mac OS X 10.5 through 10.6 and Windows, and before 4.1.1 on Mac OS X 10.4; and webkitgtk before 1.2.6; allows remote attackers to execute arbitrary code or cause a denial of service (memory corruption and application crash) via a crafted regular expression.

Integer signedness error in WebKit in Apple Safari before 5.0.1 on Mac OS X 10.5 through 10.6 and Windows, and before 4.1.1 on Mac OS X 10.4, allows remote attackers to execute arbitrary code or cause a denial of service (application crash) via vectors involving a JavaScript array index.

WebKit in Apple Safari before 5.0.1 on Mac OS X 10.5 through 10.6 and Windows, and before 4.1.1 on Mac OS X 10.4; and webkitgtk before 1.2.6; does not properly handle just-in-time (JIT) compiled JavaScript stubs, which allows remote attackers to execute arbitrary code or cause a denial of service (application crash) via a crafted HTML document, related to a "reentrancy issue."

Heap-based buffer overflow in WebKit in Apple Safari before 5.0.1 on Mac OS X 10.5 through 10.6 and Windows, and before 4.1.1 on Mac OS X 10.4, allows remote attackers to execute arbitrary code or cause a denial of service (application crash) via a JavaScript string object.

WebKit in Apple Safari before 5.0.1 on Mac OS X 10.5 through 10.6 and Windows, and before 4.1.1 on Mac OS X 10.4; and webkitgtk before 1.2.6; allows remote attackers to execute arbitrary code or cause a denial of service (memory corruption and application crash) via a use element in an SVG document.
