Vulnerabilities (CVE)

MySQL, when running on Windows, allows remote authenticated users with insert privileges on the mysql.func table to cause a denial of service (server hang) and possibly execute arbitrary code via (1) a request for a non-library file, which causes the Windows LoadLibraryEx function to block, or (2) a request for a function in a library that has the XXX_deinit or XXX_init functions defined but is not tailored for mySQL, such as jpeg1x32.dll and jpeg2x32.dll.

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

The mysql_create_function function in sql_udf.cc for MySQL 4.0 before 4.0.25, 4.1 before 4.1.13, and 5.0 before 5.0.7-beta, when running on Windows, uses an incomplete blacklist in a directory traversal check, which allows attackers to include arbitrary files via the backslash (\) character.

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.

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.

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.

Buffer overflow in the open_table function in sql_base.cc in MySQL 5.0.x up to 5.0.20 might allow remote attackers to execute arbitrary code via crafted COM_TABLE_DUMP packets with invalid length values.

MySQL 3.22 allows remote attackers to bypass password authentication and access a database via a short check string.

Format string vulnerability in time.cc in MySQL Server 4.1 before 4.1.21 and 5.0 before 1 April 2006 allows remote authenticated users to cause a denial of service (crash) via a format string instead of a date as the first parameter to the date_format function, which is later used in a formatted print call to display the error message.

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 execute arbitrary code by using CREATE FUNCTION to access libc calls, as demonstrated by using strcat, on_exit, and exit.

MySQL 5.0.18 allows local users with access to a VIEW to obtain sensitive information via the "SELECT * FROM information_schema.views;" query, which returns the query that created the VIEW. NOTE: this issue has been disputed by third parties, saying that the availability of the schema is a normal and sometimes desired aspect of database access

Double-free vulnerability in mysqld for MySQL before 3.23.55 allows attackers with MySQL access to cause a denial of service (crash) via mysql_change_user.

SQL injection vulnerability in MySQL 4.1.x before 4.1.20 and 5.0.x before 5.0.22 allows context-dependent attackers to execute arbitrary SQL commands via crafted multibyte encodings in character sets such as SJIS, BIG5, and GBK, which are not properly handled when the mysql_real_escape function is used to escape the input.

MySQL before 4.1.21, 5.0 before 5.0.25, and 5.1 before 5.1.12, when run on case-sensitive filesystems, allows remote authenticated users to create or access a database when the database name differs only in case from a database for which they have permissions.

mysqlbug in MySQL allows local users to overwrite arbitrary files via a symlink attack on the failed-mysql-bugreport temporary file.

Unknown vulnerability in MySQL 3.23.58 and earlier, when a local user has privileges for a database whose name includes a "_" (underscore), grants privileges to other databases that have similar names, which can allow the user to conduct unauthorized activities.

Stack-based buffer overflow in the mysql_real_connect function in the MySql client library (libmysqlclient) 4.0.13 and earlier allows local users to execute arbitrary code via a long socket name, a different vulnerability than CVE-2001-1453.

Buffer overflow in MySQL before 3.23.33 allows remote attackers to execute arbitrary code via a long drop database request.

MySQL 3.23.55 and earlier creates world-writeable files and allows mysql users to gain root privileges by using the "SELECT * INFO OUTFILE" operator to overwrite a configuration file and cause mysql to run as root upon restart, as demonstrated by modifying my.cnf.

MySQL 5.0.18 and earlier allows local users to bypass logging mechanisms via SQL queries that contain the NULL character, which are not properly handled by the mysql_real_query function. NOTE: this issue was originally reported for the mysql_query function, but the vendor states that since mysql_query expects a null character, this is not an issue for mysql_query.

MySQL 3.20 through 4.1.0 uses a weak algorithm for hashed passwords, which makes it easier for attackers to decrypt the password via brute force methods.

Off-by-one buffer overflow in the Instance_options::complete_initialization function in instance_options.cc in the Instance Manager in MySQL before 5.0.23 and 5.1 before 5.1.12 might allow local users to cause a denial of service (application crash) via unspecified vectors, which triggers the overflow when the convert_dirname function is called. NOTE: the vendor has disputed this issue via e-mail to CVE, saying that it is only exploitable when the user has access to the configuration file or th ... Off-by-one buffer overflow in the Instance_options::complete_initialization function in instance_options.cc in the Instance Manager in MySQL before 5.0.23 and 5.1 before 5.1.12 might allow local users to cause a denial of service (application crash) via unspecified vectors, which triggers the overflow when the convert_dirname function is called. NOTE: the vendor has disputed this issue via e-mail to CVE, saying that it is only exploitable when the user has access to the configuration file or the Instance Manager daemon. Due to intended functionality, this level of access would already allow the user to disrupt program operation, so this does not cross security boundaries and is not a vulnerability

WinMySQLadmin 1.1 stores the MySQL password in plain text in the my.ini file, which allows local users to obtain unathorized access the MySQL database.

The COM_CHANGE_USER command in MySQL 3.x before 3.23.54, and 4.x before 4.0.6, allows remote attackers to gain privileges via a brute force attack using a one-character password, which causes MySQL to only compare the provided password against the first character of the real password.

Buffer overflow in MySQL before 3.23.31 allows attackers to cause a denial of service and possibly gain privileges.

Buffer overflow in get_salt_from_password from sql_acl.cc for MySQL 4.0.14 and earlier, and 3.23.x, allows attackers with ALTER TABLE privileges to execute arbitrary code via a long Password field.

The mysqlhotcopy script in mysql 4.0.20 and earlier, when using the scp method from the mysql-server package, allows local users to overwrite arbitrary files via a symlink attack on temporary files.

Buffer overflow in the mysql_real_connect function in MySQL 4.x before 4.0.21, and 3.x before 3.23.49, allows remote DNS servers to cause a denial of service and possibly execute arbitrary code via a DNS response with a large address length (h_length).

MySQL 4.x before 4.0.21, and 3.x before 3.23.49, allows attackers to cause a denial of service (crash or hang) via multiple threads that simultaneously alter MERGE table UNIONs.

mysqld in MySQL 3.21 creates log files with world-readable permissions, which allows local users to obtain passwords for users who are added to the user database.

The COM_CHANGE_USER command in MySQL 3.x before 3.23.54, and 4.x to 4.0.6, allows remote attackers to execute arbitrary code via a long response.

libmysqlclient client library in MySQL 3.x to 3.23.54, and 4.x to 4.0.6, does not properly verify length fields for certain responses in the (1) read_rows or (2) read_one_row routines, which allows remote attackers to cause a denial of service and possibly execute arbitrary code.
