Integer overflow in QuickLook, as used in Apple Mac OS X before 10.6.7 and MobileSafari in Apple iOS before 4.2.7 and 4.3.x before 4.3.2, allows remote attackers to execute arbitrary code or cause a denial of service (memory corruption and application crash) via a Microsoft Office document with a crafted size field in the OfficeArtMetafileHeader, related to OfficeArtBlip, as demonstrated on the iPhone by Charlie Miller and Dion Blazakis during a Pwn2Own competition at CanSecWest 2011. Un desbordamiento de enteros en QuickLook, tal y como es usado en Mac OS X anterior a versión 10.6.7 y MobileSafari en iOS anterior a versión 4.2.7 y versiones 4.3.x anteriores a 4.3.2, de Apple, 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 de Microsoft Office con un campo de tamaño diseñado en OfficeArtMetafileHeader, relacionado a OfficeArtBlip, como es demostrado en el iPhone por Charlie Miller y Dion Blazakis durante una competencia de Pwn2Own en CanSecWest 2011. This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Apple Safari on the iPhone. 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 support for parsing Office files. When handling the OfficeArtMetafileHeader the process trusts the cbSize field and performs arithmetic on it before making an allocation. • http://dvlabs.tippingpoint.com/blog/2011/02/02/pwn2own-2011 http://lists.apple.com/archives/Security-announce/2011//Oct/msg00005.html http://lists.apple.com/archives/security-announce/2011//Apr/msg00000.html http://lists.apple.com/archives/security-announce/2011//Apr/msg00001.html http://lists.apple.com/archives/security-announce/2011/Mar/msg00006.html http://secunia.com/advisories/44154 http://support.apple.com/kb/HT4581 http://support.apple.com/kb/HT4607 http://support& • CWE-189: Numeric Errors •

Use-after-free vulnerability in WebKit, as used in Apple Safari before 5.0.5; iOS before 4.3.2 for iPhone, iPod, and iPad; iOS before 4.2.7 for iPhone 4 (CDMA); and possibly other products allows remote attackers to execute arbitrary code by adding children to a WBR tag and then removing the tag, related to text nodes, as demonstrated by Chaouki Bekrar during a Pwn2Own competition at CanSecWest 2011. Vulnerabilidad sin especificar en WebKit. Tal como se utiliza en Apple Safari 5.0.4 en Mac OS X 10.6.6, permite a atacantes remotos ejecutar código arbitrario a través de vectores desconocidos, como ha demostrado Chaouki Bekrar durante el concurso Pwn2Own de la CanSecWest 2011. This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of 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 way the Webkit library handles WBR tags on a webpage. • http://dvlabs.tippingpoint.com/blog/2011/02/02/pwn2own-2011 http://lists.apple.com/archives/security-announce/2011//Apr/msg00000.html http://lists.apple.com/archives/security-announce/2011//Apr/msg00001.html http://lists.apple.com/archives/security-announce/2011//Apr/msg00002.html http://secunia.com/advisories/44151 http://secunia.com/advisories/44154 http://support.apple.com/kb/HT4596 http://support.apple.com/kb/HT4607 http://twitter.com/aaronportnoy/statuses/45632544967901187&# • CWE-399: Resource Management Errors •

Photos in Apple iOS before 4.2 enables support for HTTP Basic Authentication over an unencrypted connection, which allows man-in-the-middle attackers to read MobileMe account passwords by spoofing a MobileMe Gallery server during a "Send to MobileMe" action. Fotos en Apple iOS anterior a v4.2 habilita el soporte para la autenticación básica HTTP a través de una conexión sin cifrar, lo cual permite a atacantes man-in-the-middle leer contraseñas de cuentas MobileMe mediante la suplantación de un servidor de MobileMe Gallery durante una acción "Enviar a MobileMe". • http://lists.apple.com/archives/security-announce/2010//Nov/msg00003.html http://secunia.com/advisories/42314 http://support.apple.com/kb/HT4456 http://www.securitytracker.com/id?1024771 http://www.vupen.com/english/advisories/2010/3046 https://exchange.xforce.ibmcloud.com/vulnerabilities/63420 • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •

WebKit in Apple iOS before 4.2 allows remote attackers to bypass the remote image loading setting in Mail via an HTML LINK element with a DNS prefetching property, as demonstrated by an HTML e-mail message that uses a LINK element for X-Confirm-Reading-To functionality, a related issue to CVE-2010-3813. WebKit en Apple iOS anterior a v4.2 permite a atacantes remotos evitar el ajuste de carga de imágenes remotas en mensajes a través de un elemento HTML LINK con una propiedad DNS prefetching, como lo demuestra un mensaje de correo electrónico HTML que utiliza un elemento LINK para la funcionalidad X-Confirm-Reading-To, un problema relacionado con CVE-2010-3813. • http://lists.apple.com/archives/security-announce/2010//Nov/msg00003.html http://lists.apple.com/archives/security-announce/2011//Jul/msg00002.html http://lists.opensuse.org/opensuse-security-announce/2011-01/msg00006.html http://secunia.com/advisories/42314 http://secunia.com/advisories/43068 http://support.apple.com/kb/HT4456 http://support.apple.com/kb/HT4808 http://www.securitytracker.com/id?1024773 http://www.vupen.com/english/advisories/2010/3046 http://www.vupen.co • CWE-264: Permissions, Privileges, and Access Controls •
