Descriptions

Integer underflow in the nsHtml5TreeBuilder class in the HTML5 string parser in Mozilla Firefox before 45.0 and Firefox ESR 38.x before 38.7 allows remote attackers to execute arbitrary code or cause a denial of service (use-after-free) by leveraging mishandling of end tags, as demonstrated by incorrect SVG processing, aka ZDI-CAN-3545.

Desbordamiento inferior de entero en la clase nsHtml5TreeBuilder en el intérprete de cadenas HTML5 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 o causar una denegación de servicio (uso después de liberación de memoria) mediante el aprovechamiento del manejo incorrecto de las etiquetas finales, según lo demostrado por el procesamiento incorrecto de SVG, también conocido como ZDI-CAN-3545.

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 HTML5 end tags. The issue lies in the failure to check for an index becoming negative, allowing for out-of-bounds indexing. An attacker can leverage this vulnerability to execute code within the context of the current process.
