Use-after-free vulnerability in WebKit in Apple Safari before 4.0.5 allows remote attackers to execute arbitrary code or cause a denial of service (application crash) via vectors related to the run-in Cascading Style Sheets (CSS) display property. Vulnerabilidad de uso después de la liberación en WebKit de Apple Safari anterior a la v4.0.5, permite a atacantes remotos ejecutar código de su elección o provocar una denegación de servicio (caída de la aplicación) a través de vectores relacionados con la propiedad de run-in de visualizar las Hojas de Estilo en Cascada -Cascading Style Sheets, CSS- This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Apple Safari and other WebKit based browsers. User interaction is required to exploit this vulnerability in that the target must visit a malicious page. The specific flaw exists in the handling of the run-in value for display CSS styles. A specially crafted web page can cause a use after free() condition in WebKit's WebCore::RenderBlock() method. This can be further leveraged by attackers to execute arbitrary code under the context of the current user. • http://lists.apple.com/archives/security-announce/2010/Jun/msg00003.html http://lists.apple.com/archives/security-announce/2010/Mar/msg00000.html http://lists.fedoraproject.org/pipermail/package-announce/2010-May/041383.html http://lists.fedoraproject.org/pipermail/package-announce/2010-May/041432.html http://lists.fedoraproject.org/pipermail/package-announce/2010-May/041436.html http://lists.opensuse.org/opensuse-security-announce/2011-01/msg00006.html http://osvdb.org/62948 http://secunia.com/a • CWE-399: Resource Management Errors •

Use-after-free vulnerability in WebKit in Apple Safari before 4.0.5 allows remote attackers to execute arbitrary code or cause a denial of service (application crash) via an HTML document with improperly nested tags. Vulnerabilidad uso después de la liberación (use-after-free) en Apple Safari anterior v4.0.5 permite a atacantes remotos ejecutar código de su elección o causar una denegación de servicio (caída de aplicación) a través de un documento HTML con etiquetas inadecuadamente anidadas. This vulnerability allows remote attackers to execute arbitrary code on vulnerable software utilizing Apple's WebKit library. User interaction is required to exploit this vulnerability in that the target must visit a malicious page. The specific flaw exists due to a failure to unregister a callback pointer during the destruction of a particular type of element when embedded inside a 'blink' container. The application dereferences the original resource which can can be leveraged by an attacker to execute arbitrary code under the context of the current user. • https://www.exploit-db.com/exploits/12425 http://lists.apple.com/archives/security-announce/2010/Jun/msg00003.html http://lists.apple.com/archives/security-announce/2010/Mar/msg00000.html http://lists.fedoraproject.org/pipermail/package-announce/2010-May/041383.html http://lists.fedoraproject.org/pipermail/package-announce/2010-May/041432.html http://lists.fedoraproject.org/pipermail/package-announce/2010-May/041436.html http://lists.opensuse.org/opensuse-security-announce/2011-01/msg00006.html http:&# • CWE-416: Use After Free •

Use-after-free vulnerability in WebKit in Apple Safari before 4.0.5 allows remote attackers to execute arbitrary code or cause a denial of service (application crash) via a crafted XML document. Vulnerabilidad de uso después de liberacion en WebKit de Apple Safari en versiones anteriores a la v4.0.5 permite a usuarios remotos ejecutar comandos de su elección o provocar una denegación de servicio (caida de la aplicación) a través de un documento XML modificado. 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 library's support for mouse events on a particular element. If a mouse event is dispatched to an element when one of it's attributes is undefined, the library will dereference a memory pointer pointing to arbitrary data. • http://lists.apple.com/archives/security-announce/2010/Jun/msg00003.html http://lists.apple.com/archives/security-announce/2010/Mar/msg00000.html http://lists.fedoraproject.org/pipermail/package-announce/2010-May/041383.html http://lists.fedoraproject.org/pipermail/package-announce/2010-May/041432.html http://lists.fedoraproject.org/pipermail/package-announce/2010-May/041436.html http://lists.opensuse.org/opensuse-security-announce/2011-01/msg00006.html http://secunia.com/advisories/41856 http://secu • CWE-399: Resource Management Errors •
