Description

This security bulletin contains information about 5 secuirty vulnerabilities.


1) 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.


2) 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.


3) 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.


4) 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.


5) 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.
