Double 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 an event listener in an SVG document, related to duplicate event listeners, a timer, and an AnimateTransform object. Una vulnerabilidad de doble liberación 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 un detector de eventos en un documento SVG, relacionado con detectores de eventos duplicados, un temporizador y un objeto AnimateTransform. 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 application duplicates event listeners in .svg documents. Upon creating an AnimateTransform object, the library will create a timer to handle the transformation and duplicate the object's event listener into Webkit's "shadow tree" of the image. • 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 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 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 •

The mod_dav_svn module for the Apache HTTP Server, as distributed in Apache Subversion 1.5.x and 1.6.x before 1.6.17, when the SVNPathAuthz short_circuit option is enabled, allows remote attackers to cause a denial of service (infinite loop and memory consumption) in opportunistic circumstances by requesting data. El módulo mod_dav_svn para Apache HTTP Server, como se distribuye en Apache Subersion v1.5.x y v1.6.x antes de 1.6.17, cuando la opción SVNPathAuthz short_circuit está habilitada permite a atacantes remotos a causar una denegación de servicio (bucle infinito y consumo de memoria) mediante la petición de datos en circunstancias oportunistas. • http://lists.apple.com/archives/security-announce/2012/Feb/msg00000.html http://lists.fedoraproject.org/pipermail/package-announce/2011-July/062211.html http://lists.fedoraproject.org/pipermail/package-announce/2011-June/061913.html http://secunia.com/advisories/44633 http://secunia.com/advisories/44681 http://secunia.com/advisories/44849 http://secunia.com/advisories/44888 http://secunia.com/advisories/45162 http://subversion.apache.org/security/CVE-2011-1783-advisory.txt http://support.ap •
