Уязвимость функции xbstream_open системы управления базами данных MariaDB, позволяющая нарушителю вызвать отказ в обслуживании

MariaDB Server before 10.7 is vulnerable to Denial of Service. In extra/mariabackup/ds_xbstream.cc, when an error occurs (stream_ctxt->dest_file == NULL) while executing the method xbstream_open, 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.

MariaDB Server before 10.7 is vulnerable to Denial of Service. While executing the plugin/server_audit/server_audit.c method log_statement_ex, the held lock lock_bigbuffer is not released correctly, which allows local users to trigger a denial of service due to the deadlock.

MariaDB Server before 10.7 is vulnerable to Denial of Service. In extra/mariabackup/ds_compress.cc, when an error occurs (i.e., going to the err label) while executing the method create_worker_threads, the held lock thd->ctrl_mutex 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.

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.
