Mozilla Firefox 2.x before 2.0.0.18, Thunderbird 2.x before 2.0.0.18, and SeaMonkey 1.x before 1.1.13 do not properly change the source URI when processing a canvas element and an HTTP redirect, which allows remote attackers to bypass the same origin policy and access arbitrary images that are not directly accessible to the attacker. NOTE: this issue can be leveraged to enumerate software on the client by performing redirections related to moz-icon. Mozilla Firefox 2.x versiones anteriores a v2.0.0.18, Thunderbird 2.x versiones anteriores a v2.0.0.18, y SeaMonkey 1.x versiones anteriores a v1.1.13 no cambia apropiadamente la URI origen cuando procesa un elemento CANVAS y una redirección HTTP, lo cual permite a atacantes remotos evitar las mismas políticas de origen e imágenes aleatorias de acceso que no son directamente accesibles por el atacante. NOTA: esta cuestión se puede utilizar para enumerar software en un cliente mediante redirecciones realizadas con moz-icon. • http://lists.opensuse.org/opensuse-security-announce/2008-11/msg00004.html http://scary.beasts.org/security/CESA-2008-009.html http://scarybeastsecurity.blogspot.com/2008/11/firefox-cross-domain-image-theft-and.html http://secunia.com/advisories/32684 http://secunia.com/advisories/32693 http://secunia.com/advisories/32694 http://secunia.com/advisories/32714 http://secunia.com/advisories/32715 http://secunia.com/advisories/32778 http://secunia.com/advisories/32798 http://secunia.com&# • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •

Mozilla Firefox 2.x before 2.0.0.18 and SeaMonkey 1.x before 1.1.13 do not properly check when the Flash module has been dynamically unloaded properly, which allows remote attackers to execute arbitrary code via a crafted SWF file that "dynamically unloads itself from an outside JavaScript function," which triggers an access of an expired memory address. Mozilla Firefox 2.x antes de 2.0.0.18 y SeaMonkey 1.x antes de 1.1.13 no comprueba correctamente cuando se ha descargado dinámicamente el módulo Flash, lo que permite a atacantes remotos ejecutar código de su elección mediante un archivo SWF manipulado que "se descarga dinámicamente de una función Javascript externa", lo que dispara un acceso a una dirección de memoria que ha expirado. This vulnerability allows remote attackers to execute code on vulnerable installations of Mozilla Firefox with Adobe's Flash Player. User interaction is required in that a user must visit a malicious web site. The specific flaw exists due to a failure to check whether the Flash module has been properly dynamically unloaded. If an SWF file dynamically unloads itself via an outside JavaScript function, the browser will return to an address no longer mapped to the Flash module. • http://lists.opensuse.org/opensuse-security-announce/2008-11/msg00004.html http://secunia.com/advisories/32684 http://secunia.com/advisories/32693 http://secunia.com/advisories/32694 http://secunia.com/advisories/32714 http://secunia.com/advisories/32778 http://secunia.com/advisories/32845 http://secunia.com/advisories/32853 http://secunia.com/advisories/33433 http://secunia.com/advisories/34501 http://sunsolve.sun.com/search/document.do?assetkey=1-26-256408-1 http://ubuntu • CWE-399: Resource Management Errors •

nsFrameManager in Firefox 3.x before 3.0.4, Firefox 2.x before 2.0.0.18, Thunderbird 2.x before 2.0.0.18, and SeaMonkey 1.x before 1.1.13 allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code by modifying properties of a file input element while it is still being initialized, then using the blur method to access uninitialized memory. nsFrameManager en Firefox v3.x antes de la v3.0.4, Firefox v2.x antes de la v2.0.0.18, Thunderbird 2.x antes de la v2.0.0.18, y SeaMonkey v1.x antes de la v1.1.13 permite a atacantes remotos producir una denegación de servicio (caída) y una posible ejecución de código a su elección modificación de las propiedades de un elemento de entrada de fichero mientras se inicia, cuando se esta utilizando el método blur para acceder a no ha sido inicializada. This vulnerability allows attackers to potentially execute arbitrary code on vulnerable installations of Mozilla Firefox. User interaction is required to exploit this vulnerability in that the target must visit a malicious page. The specific flaw exists when a DOM method on a specific HTML form object is called before the object itself has actually completed it's initialization. This will lead to a call of uninitialized data which can result in code execution under the context of the current user. • http://lists.opensuse.org/opensuse-security-announce/2008-11/msg00004.html http://secunia.com/advisories/32684 http://secunia.com/advisories/32693 http://secunia.com/advisories/32694 http://secunia.com/advisories/32695 http://secunia.com/advisories/32713 http://secunia.com/advisories/32714 http://secunia.com/advisories/32715 http://secunia.com/advisories/32721 http://secunia.com/advisories/32778 http://secunia.com/advisories/32798 http://secunia.com/advisories/32845 http:// • CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') •
