Description
Уязвимость процессоров Intel, ARM и AMD связана с особенностями функционирования модуля прогнозирования ветвлений. Эксплуатация уязвимости позволяет нарушителю получить доступ к защищенной памяти из программы, не обладающей соответствующими привилегиями, путём использования механизма прогнозирования косвенных переходов

Recommendations

Возможны следующие меры по устранению уязвимости:
-
вариант 1: на аппаратном уровне;
-
вариант 2: на системном уровне;
-
вариант 3: на прикладном уровне.
Первый вариант предполагает замену процессора, однако данный вариант трудно реализуем на практике.
Наиболее актуален второй вариант, предполагающий установку обновления, выпущенного разработчиками системного программного обеспечения.
Третий вариант применим к браузерам и возможен лишь для противодействия векторам атак, связанных с использованием JavaScript.
Подробные рекомендации по устранению представлены на сайтах разработчиков программного обеспечения:
