Unspecified vulnerability in the MySQL Server component in Oracle MySQL 5.5.26 and earlier allows remote authenticated users to affect confidentiality, related to MySQL Client.

Unspecified vulnerability in the MySQL Server component in Oracle MySQL 5.5.26 and earlier allows remote attackers to affect integrity and availability, related to MySQL Client.

Unspecified vulnerability in the MySQL Server component in Oracle MySQL 5.5.26 and earlier allows remote authenticated users to affect availability via unknown vectors related to Server.

MySQL 5.0.88, and possibly other versions and platforms, allows local users to bypass certain privilege checks by calling CREATE TABLE on a MyISAM table with modified (1) DATA DIRECTORY or (2) INDEX DIRECTORY arguments that are originally associated with pathnames without symlinks, and that can point to tables created at a future time at which a pathname is modified to contain a symlink to a subdirectory of the MySQL data home directory, related to incorrect calculation of the mysql_unpacked_real_data_home value. NOTE: this vulnerability exists because of a CVE-2009-4030 regression, which was not omitted in other packages and versions such as MySQL 5.0.95 in Red Hat Enterprise Linux 6.

Unspecified vulnerability in the MySQL Server component in Oracle MySQL 5.5.19 and earlier allows remote authenticated users to affect availability via unknown vectors related to Server Optimizer.

Unspecified vulnerability in the MySQL Server component in Oracle MySQL 5.1.60 and earlier, and 5.5.19 and earlier, allows remote authenticated users to affect availability, related to MyISAM.

MySQL before 5.1.48 allows remote authenticated users with alter database privileges to cause a denial of service (server crash and database loss) via an ALTER DATABASE command with a #mysql50# string followed by a . (dot), .. (dot dot), ../ (dot dot slash) or similar sequence, and an UPGRADE DATA DIRECTORY NAME command, which causes MySQL to move certain directories to the server data directory.

The in_decimal::set function in item_cmpfunc.cc in MySQL before 5.0.40, and 5.1 before 5.1.18-beta, allows context-dependent attackers to cause a denial of service (crash) via a crafted IF clause that results in a divide-by-zero error and a NULL pointer dereference.

MySQL 4.1 before 4.1.21 and 5.0 before 5.0.24 allows a local user to access a table through a previously created MERGE table, even after the user's privileges are revoked for the original table, which might violate intended security policy.

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.

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.

MySQL 3.x before 3.23.59, 4.x before 4.0.19, 4.1.x before 4.1.2, and 5.x before 5.0.1, checks the CREATE/INSERT rights of the original table instead of the target table in an ALTER TABLE RENAME operation, which could allow attackers to conduct unauthorized activities.

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.

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.

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

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.

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.

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 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.
