Уязвимость выполнения произвольного JavaScript-кода с правами chrome в Mozilla Firefox, Thunderbird и SeaMonkey через модификацию прототипа объекта
Описание
В реализации Chrome Object Wrapper (COW) в Mozilla Firefox, Thunderbird и SeaMonkey не предотвращается модификация прототипа объекта. Это позволяет злоумышленникам выполнить произвольный JavaScript-код с правами chrome путем обращения к Object.prototype.__proto__ в специально созданном HTML-документе.
Затронутые версии ПО
- Mozilla Firefox до версии 18.0
- Mozilla Firefox ESR 17.x до версии 17.0.2
- Thunderbird до версии 17.0.2
- Thunderbird ESR 17.x до версии 17.0.2
- SeaMonkey до версии 2.15
