DSA-273-1 krb4 -- криптографическая слабость

Дата сообщения:

28.03.2003

Затронутые пакеты:

Уязвим:

Да

Ссылки на базы данных по безопасности:

В каталоге Mitre CVE: CVE-2003-0138, CVE-2003-0139.
База данных CERT по уязвимостям, предложениям и инцидентам: VU#623217, VU#442569.

Более подробная информация:

Криптографическая слабость 4 версии протокола Kerberos позволяет нападающему использовать атаку на подбор текста, чтобы выдать себя за любой авторитетный источник. Другие уязвимые места реализации krb4, включённой в дистрибутив krb4 MIT, позволяют использовать атаку "вырезать и вставить" для изготовления билетов krb4 неавторизованных клиентов-авторитетных источников, если сервер krb4 использует ключи 3DES. Эти атаки могут подорвать всю инфраструктуру аутентификации на основе Kerberos сайта.

В стабильном дистрибутиве (woody) эта проблема исправлена в версии 1.1-8-2.3.

В старом стабильном дистрибутиве (potato) эта проблема исправлена в версии 1.0-2.3.

В нестабильном дистрибутиве (sid) эта проблема исправлена в версии 1.2.2-1.

Мы рекомендуем вам немедленно обновить пакет krb4.

Исправлено в:

Debian GNU/Linux 2.2 (potato)
