Stack-based buffer overflow in the init_syms function in MySQL 4.0 before 4.0.25, 4.1 before 4.1.13, and 5.0 before 5.0.7-beta allows remote authenticated users who can create user-defined functions to execute arbitrary code via a long function_name field.

Buffer overflow in libmysqlclient.so in MySQL 3.23.33 and earlier allows remote attackers to execute arbitrary code via a long host parameter.

MySQL Database Engine uses a weak authentication method which leaks information that could be used by a remote attacker to recover the password.

security flaw

mysql_install_db in MySQL 4.1.x before 4.1.12 and 5.x up to 5.0.4 creates the mysql_install_db.X file with a predictable filename and insecure permissions, which allows local users to execute arbitrary SQL commands by modifying the file's contents.

MySQL 4.1.9, and possibly earlier versions, allows remote attackers with certain privileges to cause a denial of service (application crash) via a use command followed by an MS-DOS device name such as (1) LPT1 or (2) PRN.

The default configuration in MySQL 3.20.32 through 3.23.52, when running on Windows, does not have logging enabled, which could allow remote attackers to conduct activities without detection.

MySQL allows local users to modify passwords for arbitrary MySQL users via the GRANT privilege.

security flaw

MySQL 4.0.23 and earlier, and 4.1.x up to 4.1.10, uses predictable file names when creating temporary tables, which allows local users with CREATE TEMPORARY TABLE privileges to overwrite arbitrary files via a symlink attack.

security flaw

MySQL 4.0.23 and earlier, and 4.1.x up to 4.1.10, allows remote authenticated users with INSERT and DELETE privileges to bypass library path restrictions and execute arbitrary libraries by using INSERT INTO to modify the mysql.func table, which is processed by the udf_init function.

The default configuration of MySQL 3.20.32 through 3.23.52, when running on Windows, does set the bind address to the loopback interface, which allows remote attackers to connect to the database.

mysql: mysqlaccess creates/overwrite files on the system

The mysqlaccess script in MySQL 4.0.23 and earlier, 4.1.x before 4.1.10, 5.0.x before 5.0.3, and other versions including 3.x, allows local users to overwrite arbitrary files or read temporary files via a symlink attack on temporary files.

security flaw

MySQL before 3.23.31 allows users with a MySQL account to use the SHOW GRANTS command to obtain the encrypted administrator password from the mysql.user table and possibly gain privileges via password cracking.

Buffer overflow in the prepared statements API in libmysqlclient for MySQL 4.1.3 beta and 4.1.4 allows remote attackers to cause a denial of service via a large number of placeholders.

The default configuration of the Windows binary release of MySQL 3.23.2 through 3.23.52 has a NULL root password, which could allow remote attackers to gain unauthorized root access to the MySQL database.

curl: NTLMv2 type-3 header stack buffer overflow

libcurl versions from 7.36.0 to before 7.64.0 are vulnerable to a stack-based buffer overflow. The function creating an outgoing NTLM type-3 header (`lib/vauth/ntlm.c:Curl_auth_create_ntlm_type3_message()`), generates the request HTTP header contents based on previously received data. The check that exists to prevent the local buffer from getting overflowed is implemented wrongly (using unsigned math) and as such it does not prevent the overflow from happening. This output data can grow larger than the local buffer if very large 'nt response' data is extracted from a previous NTLMv2 header provided by the malicious or broken HTTP server. Such a 'large value' needs to be around 1000 bytes or more. The actual payload data copied to the target buffer comes from the NTLMv2 type-2 response header.

mysql: General unspecified vulnerability (CPU Jul 2025)

Vulnerability in the MySQL Cluster product of Oracle MySQL (component: Cluster: General). Supported versions that are affected are 8.0.0-8.0.42, 8.4.0-8.4.5 and 9.0.0-9.3.0. Easily exploitable vulnerability allows high privileged attacker with logon to the infrastructure where MySQL Cluster executes to compromise MySQL Cluster. Successful attacks of this vulnerability can result in takeover of MySQL Cluster. CVSS 3.1 Base Score 6.7 (Confidentiality, Integrity and Availability impacts). CVSS Vector: (CVSS:3.1/AV:L/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H).

zlib: Undefined left shift of negative number

The inflateMark function in inflate.c in zlib 1.2.8 might allow context-dependent attackers to have unspecified impact via vectors involving left shifts of negative integers.

mysql: Server : Security : Firewall unspecified vulnerability (CPU Jan 2024)

Vulnerability in the MySQL Server product of Oracle MySQL (component: Server : Security : Firewall). Supported versions that are affected are 8.0.35 and prior and 8.2.0 and prior. Difficult to exploit vulnerability allows high privileged attacker with network access via multiple protocols to compromise MySQL Server.
