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. 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 botones HTML. This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Apple Safari's Webkit. Authentication is not required to exploit this vulnerability. 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 Webkit's support of the 'first-letter' css style. • http://lists.apple.com/archives/security-announce/2010//Jun/msg00002.html http://lists.apple.com/archives/security-announce/2010//Nov/msg00003.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://sec • CWE-399: Resource Management Errors •

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, accesses uninitialized memory during the handling of a use element in an SVG document, which allows remote attackers to execute arbitrary code or cause a denial of service (application crash) via a crafted document containing XML that triggers a parsing error, related to ProcessInstruction. 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, accede a la memoria no inicializada durante el manejo de un elemento de uso en un documento SVG, que permite a atacantes remotos ejecutar código arbitrario o causar una denegación de servicio (bloqueo de aplicación) por medio de un documento especialmente diseñado que contiene XML que desencadena un error de análisis relacionado con ProcessInstruction. 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 with how WebKit inserts error messages into documents utilizing the SVG namespace. Upon a parsing error the library will attempt to access an element before repairing the XML. • http://lists.apple.com/archives/security-announce/2010//Jun/msg00002.html http://lists.apple.com/archives/security-announce/2010//Nov/msg00003.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://sec • 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 a layout change during selection rendering and the DOCUMENT_POSITION_DISCONNECTED attribute in a container of an unspecified type. Una vulnerabilidad de uso de la memoria previamente liberada 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 a un cambio de diseño durante la renderización de selección y el atributo DOCUMENT_POSITION_DISCONNECTED en un contenedor de un tipo no especificado. This vulnerability allows remote attackers to execute arbitrary code on software utilizing a vulnerable version of Apple's Webkit. User interaction is required to exploit this vulnerability in that the target must visit a malicious page. The specific flaw exists within the way that Apple's Webkit handles the DOCUMENT_POSITION_DISCONNECTED attribute when a container is removed. This attribute is responsible for ensuring that a node is disconnected from it's container and is implementation specific regarding the order of each 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-399: Resource Management Errors •

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, accesses uninitialized memory during a selection change on a form input element, which allows remote attackers to execute arbitrary code or cause a denial of service (application crash) via a crafted HTML document. 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, accede a memoria no inicializada durante un cambio de selección en un elemento input de un formulario, lo cual permite a los atacantes remotos ejecutar código a su elección o causar una denegación de servicio (fallo de la aplicación) a través de documentos HTML manipulados. 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 viewing a website. The specific flaw exists within the way the library handles selections. If a particular element is selected by the application, an event can be triggered in order to interrupt execution handling a component of the selection. • 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/43068 http://securitytracker.com/id?1024067 http://support.apple.com/kb/HT4196 http://s • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •
