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 an SVG document that contains recursive Use elements, which are not properly handled during page deconstruction. 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 un documento SVG que contiene elementos de uso recursivo, que no se manejan apropiadamente durante la deconstrucción de la página. 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 WebKit library handles recursively defined Use elements. Upon expanding the target of the use element within the tree, the application will create a dual-reference of a Use element. • 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 •

WebKit.dll in WebKit, as used in Safari.exe 4.531.9.1 in Apple Safari, allows remote attackers to cause a denial of service (application crash) via JavaScript that writes <marquee> sequences in an infinite loop. WebKit.dll de WebKit, como el utilizado en Safari.exe v4.531.9.1 en Apple Safari permite a atacantes remotos provocar una denegación de servicio (caída de la aplicación) mediante un JavaScript que escribe secuencias <marquee> en un bucle infinito. • http://h.ackack.net/?p=258 http://lists.opensuse.org/opensuse-security-announce/2011-01/msg00006.html http://secunia.com/advisories/43068 http://www.vupen.com/english/advisories/2011/0212 • CWE-399: Resource Management Errors •

The JavaScript implementation in WebKit allows remote attackers to send selected keystrokes to a form field in a hidden frame, instead of the intended form field in a visible frame, via certain calls to the focus method. La implementación de JavaScript en WebKit permite a usuarios remotos enviar pulsaciones de teclado seleccionadas a un campo de formulario en un frame oculto, en lugar del campo del frame visible, a través de varias llamadas al método focus. • http://lists.opensuse.org/opensuse-security-announce/2011-01/msg00006.html http://secunia.com/advisories/43068 http://www.securityfocus.com/archive/1/510070/100/0/threaded http://www.vupen.com/english/advisories/2011/0212 https://bugzilla.mozilla.org/show_bug.cgi?id=552255 • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •
