- Дата сообщения:
- 15.03.2003
- Затронутые пакеты:
- samba
- Уязвим:
- Да
- Ссылки на базы данных по безопасности:
- В базе данных Bugtraq (на SecurityFocus): Идентификатор BugTraq 7107, Идентификатор BugTraq 7106.
В каталоге Mitre CVE: CVE-2003-0085, CVE-2003-0086. - Более подробная информация:
-
Себастьян Крамер (Sebastian Krahmer) из команды проверки безопасности SuSE обнаружил две проблемы в samba, популярной реализации SMB/CIFS:
- переполнение буфера в коде пересборки фрагментов пакета SMB/CIFS, используемом smbd. Поскольку smbd выполняется с привилегиями суперпользователя, нападающий может использовать эту уязвимость для присвоения прав доступа суперпользователя на машине, где работает smbd.
- код, записывающий файлы reg уязвим к особому способу использования chown, что позволяет локальным пользователям переписать системные файлы.
Обе проблемы исправлены в версии исходной программы 2.2.8 и в пакете для Debian GNU/Linux 3.0/woody версии 2.2.3a-12.1.
- Исправлено в:
