Description
This security bulletin contains information about 12 secuirty vulnerabilities.
1) Resource exhaustion (CVE-ID: CVE-2021-46657)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to application does not properly control consumption of internal resources when processing certain subquery uses of ORDER BY. A remote attacker can trigger resource exhaustion and perform a denial of service (DoS) attack.
2) Resource exhaustion (CVE-ID: CVE-2021-46658)
The vulnerability allows a local user to perform a denial of service (DoS) attack.
The vulnerability exists due to improper handling of with_window_func=true for a subquery. A local user can trigger resource exhaustion and perform a denial of service (DoS) attack.
3) Resource management error (CVE-ID: CVE-2021-46659)
The vulnerability allows a remote user to perform a denial of service (DoS) attack.
The vulnerability exists due to improper management of internal resources. The database does not recognize that SELECT_LEX::nest_level is local to each VIEW. A remote user execute a specially crafted statements and perform a denial of service (DoS) attack.
4) Input validation error (CVE-ID: CVE-2021-46661)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to application crash in find_field_in_tables and find_order_in_list via an unused common table expression (CTE). A remote attacker can pass specially crafted input to the application and perform a denial of service (DoS) attack.
5) Input validation error (CVE-ID: CVE-2021-46663)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to ha_maria::extra application crash via certain SELECT statements. A remote attacker can pass specially crafted input to the application and perform a denial of service (DoS) attack.
6) NULL pointer dereference (CVE-ID: CVE-2021-46664)
The vulnerability allows a remote user to perform a denial of service (DoS) attack.
The vulnerability exists due to a NULL pointer dereference error in the sub_select_postjoin_aggr() function. A remote user can pass specially crafted data to the application and perform a denial of service (DoS) attack.
7) Input validation error (CVE-ID: CVE-2021-46665)
The vulnerability allows a remote user to perform a denial of service (DoS) attack.
The vulnerability exists due to incorrect used_tables expectations in the sql_parse.cc. A remote user can pass specially crafted input to the application and perform a denial of service (DoS) attack.
8) Resource exhaustion (CVE-ID: CVE-2021-46668)
The vulnerability allows a remote user to perform a denial of service (DoS) attack.
The vulnerability exists due to application does not properly control consumption of internal resources. A remote user can trigger resource exhaustion via certain long SELECT DISTINCT statements that improperly interact with storage-engine resource limitations for temporary data structures.
9) Buffer overflow (CVE-ID: CVE-2022-24048)
The vulnerability allows a remote user to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error in the storage engine when processing CONNECT queries. A remote authenticated user can send a specially crafted SQL query to the affected database instance, trigger a memory corruption and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
10) Use-after-free (CVE-ID: CVE-2022-24050)
The vulnerability allows a remote user to compromise vulnerable system.
The vulnerability exists due to a use-after-free error in the storage engine when processing CONNECT queries. A remote user can send a specially crafted SQL query to the database instance, trigger a use-after-free error and execute arbitrary code on the system.
Successful exploitation of the vulnerability may allow an attacker to compromise vulnerable system.
11) Format string error (CVE-ID: CVE-2022-24051)
The vulnerability allows a remote user to execute arbitrary code on the target system.
The vulnerability exists due to a format string error in the CONNECT function implementation. A remote user with access to database can send a specially crafted SQL query that contains format string specifiers and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
12) Heap-based buffer overflow (CVE-ID: CVE-2022-24052)
The vulnerability allows a remote user to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error in the storage engine when processing CONNECT requests. A remote user can send a specially crafted SQL query to the database instance, trigger a heap-based buffer overflow and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
