Уязвимость DoS атаки из-за некорректного снятия блокировки в MariaDB Server
Описание
В MariaDB Server в extra/mariabackup/ds_compress.cc, метод create_worker_threads некорректно снимает блокировку при возникновении ошибки (если pthread_create возвращает ненулевое значение), что позволяет локальным пользователям инициировать DoS атаку из-за взаимоблокировки ресурсов. Примечание: Вендор утверждает, что это просто ошибка блокировки и не является уязвимостью с неблагоприятными последствиями.

** DISPUTED ** MariaDB Server before 10.7 is vulnerable to Denial of Service. In extra/mariabackup/ds_compress.cc, when an error occurs (pthread_create returns a nonzero value) while executing the method create_worker_threads, the held lock is not released correctly, which allows local users to trigger a denial of service due to the deadlock. Note: The vendor argues this is just an improper locking bug and not a vulnerability with adverse effects.
