Descriptions

Use-after-free vulnerability in the nsHTMLDocument::SetBody function in dom/html/nsHTMLDocument.cpp in Mozilla Firefox before 45.0 and Firefox ESR 38.x before 38.7 allows remote attackers to execute arbitrary code by leveraging mishandling of a root element, aka ZDI-CAN-3574.

Vulnerabilidad de uso después de liberación de memoria en la función nsHTMLDocument::SetBody en dom/html/nsHTMLDocument.cpp en Mozilla Firefox en versiones anteriores a 45.0 y Firefox ESR 38.x en versiones anteriores a 38.7 permite a atacantes remotos ejecutar código arbitrario mediante el aprovechamiento del manejo incorrecto de un elemento root, también conocido como ZDI-CAN-3574.

This vulnerability allows remote attackers to 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 or open a malicious file.
The specific flaw exists within the handling of nsHTMLDocument objects. By manipulating a document's elements an attacker can force a nsHTMLDocument object in memory to be reused after it has been freed. An attacker can leverage this vulnerability to execute code under the context of the current process.
