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, Apple Safari before 4.1 on Mac OS X 10.4, and Google Chrome before 5.0.375.70 does not properly handle a transformation of a text node that has the IBM1147 character set, which allows remote attackers to execute arbitrary code or cause a denial of service (memory corruption and application crash) via a crafted HTML document containing a BR element, related to a "type checking issue." WebKit en Safari de Apple anterior a versión 5.0 sobre Mac OS X versiones 10.5 hasta 10.6 y Windows, Safari de Apple anterior a versión 4.1 sobre Mac OS X versión 10.4 y Chrome de Google anterior a versión 5.0.375.70, no maneja apropiadamente una transformación de un nodo de texto que tiene el conjunto de caracteres IBM1147, 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 que contiene un elemento BR, relacionado con un "type checking issue." This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Apple Safari'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 Webkit's support of character sets. If the IBM1147 character set is applied to a particular element and that element has a text transformation applied to it, the application will attempt to access an object that doesn't exist in order to perform the transformation. • http://code.google.com/p/chromium/issues/detail?id=43487 http://googlechromereleases.blogspot.com/2010/06/stable-channel-update.html 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//Sep/msg00002.html http://lists.apple.com/archives/security-announce/2010/Jun/msg00000.html http://lists.opensuse.org/opensuse-security-announce/2011-01/msg0 • CWE-94: Improper Control of Generation of Code ('Code Injection') •

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. 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 con la propiedad de ejecución de Cascading Style Sheets (CSS) y múltiples invocaciones de un destructor para un elemento hijo al que ha sido referenciado varias veces. This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Apple Safari'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 the application's support of the run-in display property. On insertion of a specific element with the "run-in" display property, the application will create a duplicate reference of a child element used to support that attribute. • http://lists.apple.com/archives/security-announce/2010//Jun/msg00002.html http://lists.apple.com/archives/security-announce/2010/Jun/msg00000.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://support.apple.com/kb/HT4220 http://www.securityfocus.com/archive/1/511725& • CWE-399: Resource Management Errors •
