Descriptions

Use-after-free vulnerability in the nsGenericHTMLElement::GetWidthHeightForImage function in Mozilla Firefox before 29.0, Firefox ESR 24.x before 24.5, Thunderbird before 24.5, and SeaMonkey before 2.26 allows remote attackers to execute arbitrary code or cause a denial of service (heap memory corruption) via vectors involving an imgLoader object that is not properly handled during an image-resize operation.

Vulnerabilidad de uso después de liberación en la función nsGenericHTMLElement::GetWidthHeightForImage en Mozilla Firefox anterior a 29.0, Firefox ESR 24.x anterior a 24.5, Thunderbird anterior a 24.5 y SeaMonkey anterior a 2.26 permite a atacantes remotos ejecuatr código arbitrario o causar una denegación de servicio (corrupción de memoria dinámica) a través de vectores involucrando un objeto imgLoader que no se maneja debidamente durante una operación de dimensionamiento de imagen.

Bobby Holley, Carsten Book, Christoph Diehl, Gary Kwong, Jan de Mooij, Jesse Ruderman, Nathan Froyd, John Schoenick, Karl Tomlinson, Vladimir Vukicevic and Christian Holler discovered multiple memory safety issues in Firefox. If a user were tricked in to opening a specially crafted website, an attacker could potentially exploit these to cause a denial of service via application crash, or execute arbitrary code with the privileges of the user invoking Firefox. An out of bounds read was discovered in Web Audio. An attacker could potentially exploit this cause a denial of service via application crash or execute arbitrary code with the privileges of the user invoking Firefox. Various other issues were also addressed.
