ALSA-2022:6443 advisory.

  - MariaDB before 10.7.2 allows an application crash because it does not recognize that
    SELECT_LEX::nest_level is local to each VIEW. (CVE-2021-46659)

  - MariaDB through 10.5.9 allows an application crash in find_field_in_tables and find_order_in_list via an
    unused common table expression (CTE). (CVE-2021-46661)

  - MariaDB through 10.5.13 allows a ha_maria::extra application crash via certain SELECT statements.
    (CVE-2021-46663)

  - MariaDB through 10.5.9 allows an application crash in sub_select_postjoin_aggr for a NULL value of aggr.
    (CVE-2021-46664)

  - MariaDB through 10.5.9 allows a sql_parse.cc application crash because of incorrect used_tables
    expectations. (CVE-2021-46665)

  - MariaDB through 10.5.9 allows an application crash via certain long SELECT DISTINCT statements that
    improperly interact with storage-engine resource limitations for temporary data structures.
    (CVE-2021-46668)

  - MariaDB through 10.5.9 allows attackers to trigger a convert_const_to_int use-after-free when the BIGINT
    data type is used. (CVE-2021-46669)

  - Vulnerability in the MySQL Server product of Oracle MySQL (component: Server: FTS). Supported versions
    that are affected are 5.7.37 and prior and 8.0.28 and prior. Easily exploitable vulnerability allows high
    privileged attacker with network access via multiple protocols to compromise MySQL Server. Successful
    attacks of this vulnerability can result in unauthorized ability to cause a hang or frequently repeatable
    crash (complete DOS) of MySQL Server. (CVE-2022-21427)

  - MariaDB CONNECT Storage Engine Stack-based Buffer Overflow Privilege Escalation Vulnerability. This
    vulnerability allows local attackers to escalate privileges on affected installations of MariaDB.
    Authentication is required to exploit this vulnerability. The specific flaw exists within the processing
    of SQL queries. The issue results from the lack of proper validation of the length of user-supplied data
    prior to copying it to a fixed-length stack-based buffer. An attacker can leverage this vulnerability to
    escalate privileges and execute arbitrary code in the context of the service account. Was ZDI-CAN-16191.
    (CVE-2022-24048)

  - MariaDB CONNECT Storage Engine Use-After-Free Privilege Escalation Vulnerability. This vulnerability
    allows local attackers to escalate privileges on affected installations of MariaDB. Authentication is
    required to exploit this vulnerability. The specific flaw exists within the processing of SQL queries. The
    issue results from the lack of validating the existence of an object prior to performing operations on the
    object. An attacker can leverage this vulnerability to escalate privileges and execute arbitrary code in
    the context of the service account. Was ZDI-CAN-16207. (CVE-2022-24050)

  - MariaDB CONNECT Storage Engine Format String Privilege Escalation Vulnerability. This vulnerability allows
    local attackers to escalate privileges on affected installations of MariaDB. Authentication is required to
    exploit this vulnerability. The specific flaw exists within the processing of SQL queries. The issue
    results from the lack of proper validation of a user-supplied string before using it as a format
    specifier. An attacker can leverage this vulnerability to escalate privileges and execute arbitrary code
    in the context of the service account. Was ZDI-CAN-16193. (CVE-2022-24051)

  - MariaDB CONNECT Storage Engine Heap-based Buffer Overflow Privilege Escalation Vulnerability. This
    vulnerability allows local attackers to escalate privileges on affected installations of MariaDB.
    Authentication is required to exploit this vulnerability. The specific flaw exists within the processing
    of SQL queries. The issue results from the lack of proper validation of the length of user-supplied data
    prior to copying it to a fixed-length heap-based buffer. An attacker can leverage this vulnerability to
    escalate privileges and execute arbitrary code in the context of the service account. Was ZDI-CAN-16190.

  - An issue in the component Create_tmp_table::finalize of MariaDB Server v10.7 and below was discovered to
    allow attackers to cause a Denial of Service (DoS) via specially crafted SQL statements. (CVE-2022-27378)

  - An issue in the component Arg_comparator::compare_real_fixed of MariaDB Server v10.6.2 and below was
    discovered to allow attackers to cause a Denial of Service (DoS) via specially crafted SQL statements.
    (CVE-2022-27379)

  - An issue in the component my_decimal::operator= of MariaDB Server v10.6.3 and below was discovered to
    allow attackers to cause a Denial of Service (DoS) via specially crafted SQL statements. (CVE-2022-27380)

  - An issue in the component Field::set_default of MariaDB Server v10.6 and below was discovered to allow
    attackers to cause a Denial of Service (DoS) via specially crafted SQL statements. (CVE-2022-27381)

    Binary_string::free_buffer() at /sql/sql_string.h. (CVE-2022-27458)

  - 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. (CVE-2022-31622)

  - 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. (CVE-2022-31623)
