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 perform ordered list insertions, which allows remote attackers to execute arbitrary code or cause a denial of service (memory corruption and application crash) via a crafted HTML document, related to the insertion of an unspecified element into an editable container and the access of an uninitialized element. WebKit en Safari de Apple anterior a versión 5.0 sobre Mac OS X versiones 10.5 hasta 10.6 y Windows, y anterior a versión 4.1 sobre Mac OS X versión 10.4, no realiza apropiadamente las inserciones de lista ordenadas, lo que permite a los atacantes remotos ejecutar código arbitrario o causar una denegación de servicio (corrupción de memoria y bloqueo de aplicación) por medio de un documento HTML especialmente diseñado, relacionado con la inserción de un elemento no especificado hacia un contenedor editable y el acceso de un elemento no inicializado. This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Apple's Webkit. User interaction is required in that a user must be coerced into visiting a malicious website. The specific flaw exists within the way Webkit inserts an element into an editable container. Immediately before the actual insertion the library will manipulate the contents of the field in order to insert the new node. • http://lists.apple.com/archives/security-announce/2010//Jun/msg00002.html http://lists.apple.com/archives/security-announce/2010/Jun/msg00000.html http://lists.apple.com/archives/security-announce/2010/Jun/msg00003.html http://lists.opensuse.org/opensuse-security-announce/2011-01/msg00006.html http://secunia.com/advisories/40105 http://secunia.com/advisories/40196 http://secunia.com/advisories/41856 http://secunia.com/advisories/43068 http://securitytracker.com/id?1024067 http://supp • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •

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 contentEditable attribute and removing container elements. Vulnerabilidad de uso despues de liberacion en WebKit de Apple Safari anterior a v5.0 en Mac OS X v10.5 a v10.6 y Windows, y anterior a v4.1 en Mac OS X v10.4, permite a los atacantes remotos ejecutar código a su elección o causar una denegación de servicio (fallo de la aplicación) a través de vectores relacionados con la eliminación de elementos contenedores. This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Apples Webkit. User interaction is required in that the user must coerced into visiting a website or opening a malicious document. The specific flaw exists within how the library removes a particular container element containing another element holding the contentEditable attribute. Upon removal of the container during a particular event, the library will traverse the tree and access the contentEditable element that was freed. • http://lists.apple.com/archives/security-announce/2010//Jun/msg00002.html http://lists.apple.com/archives/security-announce/2010/Jun/msg00000.html http://lists.apple.com/archives/security-announce/2010/Jun/msg00003.html http://lists.opensuse.org/opensuse-security-announce/2011-01/msg00006.html http://secunia.com/advisories/40105 http://secunia.com/advisories/40196 http://secunia.com/advisories/41856 http://secunia.com/advisories/43068 http://securitytracker.com/id?1024067 http://supp • CWE-399: Resource Management Errors •

Double 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 an event listener in an SVG document, related to duplicate event listeners, a timer, and an AnimateTransform object. Una vulnerabilidad de doble liberación en WebKit en Safari de Apple anterior a versión 5.0 sobre Mac OS X versiones 10.5 hasta 10.6 y Windows, y anterior a versión 4.1 sobre Mac OS X versión 10.4, permite a los atacantes remotos ejecutar código arbitrario o causar una denegación de servicio (bloqueo de aplicación) por medio de vectores relacionados con un detector de eventos en un documento SVG, relacionado con detectores de eventos duplicados, un temporizador y un objeto AnimateTransform. This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Apple's Webkit. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file. The specific flaw exists within how the application duplicates event listeners in .svg documents. Upon creating an AnimateTransform object, the library will create a timer to handle the transformation and duplicate the object's event listener into Webkit's "shadow tree" of the image. • http://lists.apple.com/archives/security-announce/2010//Jun/msg00002.html http://lists.apple.com/archives/security-announce/2010/Jun/msg00000.html http://lists.apple.com/archives/security-announce/2010/Jun/msg00003.html http://lists.opensuse.org/opensuse-security-announce/2011-01/msg00006.html http://secunia.com/advisories/40105 http://secunia.com/advisories/40196 http://secunia.com/advisories/41856 http://secunia.com/advisories/43068 http://securitytracker.com/id?1024067 http://supp • CWE-399: Resource Management Errors •
