Обнаруживает CVE-2020-16898 и CVE-2020-16899: «Bad Neighbor»

Быстрый старт

Если у вас уже установлены Zeek и zkg, просто выполните:

.. code-block:: console

zkg install https://github.com/esnet-security/cve-2020-16898

Если установка выполняется в кластере, установите пакет на менеджере, а затем разверните его с помощью:

.. code-block:: console

zeekctl deploy

Обновление и выгрузка

Для управления версиями мы используем SemVer <http://semver.org/>. Доступные версии перечислены в тегах этого репозитория <../../tags>. Вы можете передать команде install дополнительный аргумент с нужной версией.

Чтобы обновиться до последней версии, выполните:

.. code-block:: console

zkg upgrade cve-2020-16898

Вы можете изменить приведённую выше команду, заменив upgrade на:

• unload — настраивает Zeek на то, чтобы не загружать пакет при запуске.
• load — настраивает Zeek на загрузку пакета при запуске (по умолчанию после установки).
• remove — удаляет пакет из системы.

Если вы работаете в кластере, после любого из перечисленных выше изменений необходимо повторно выполнить zeekctl deploy.
