Buffer overflow in MySQL 5.0 through 5.0.91 and 5.1 before 5.1.47 allows remote authenticated users to execute arbitrary code via a COMFIELDLIST command with a long table name.

Directory traversal vulnerability in MySQL 5.0 through 5.0.91 and 5.1 before 5.1.47 allows remote authenticated users to bypass intended table grants to read field definitions of arbitrary tables, and on 5.1 to read or delete content of arbitrary tables, via a .. (dot dot) in a table name.

The mynetskiprest function in sql/netserv.cc in MySQL 5.0 through 5.0.91 and 5.1 before 5.1.47 allows remote attackers to cause a denial of service (CPU and bandwidth consumption) by sending a large number of packets that exceed the maximum length.

MySQL before 5.1.46 allows local users to delete the data and index files of another user's MyISAM table via a symlink attack in conjunction with the DROP TABLE command, a different vulnerability than CVE-2008-4098 and CVE-2008-7247.

A denial of service flaw was found in the way MySQL processed EXPLAIN statements for SQL queries of the form:

SELECT ... UNION ... ORDER BY (SELECT ... WHERE ...)

A remote authenticated MySQL user could use this flaw to cause mysqld deamon crash (dereference NULL pointer).

Note: This issue only causes a temporary denial of service, as the mysql daemon shipped with Red Hat Enterprise Linux 5 will be automatically restarted after the crash.

A denial of service flaw was found in the way MySQL processed alternate read requests from two indexes on a table using the HANDLER interface. A remote, authenticated MySQL user could use this flaw to cause mysqld daemon abort.

A denial of service flaw was found in the way MySQL processed multiple parallel connections changing InnoDB storage engine configuration parameters (innodbfileformat and innodbfilepertable) and simultaneously issuing data definition language (DDL) statemens. A remote, authenticated MySQL user could use this flaw to cause mysqld daemon abort (assertion failure).

A denial of service flaw was found in the way MySQL processed SQL queries containing IN or CASE statements, when NULL argument was provided as one of the arguments to the query. A remote MySQL user could use this flaw to cause myqld daemon crash (dereference a NULL pointer).

MySQL improperly handled LOAD DATA INFILE requests (it did not check for SQL errors and sent an OK packet even when errors were already reported). A remote, authenticated MySQL user could use this flaw to cause mysqld daemon abort (assertion failure).

A use of unassigned memory was found in the way MySQL processed certain values provided to the BINLOG statement. A remote attacker could use this flaw to cause denial of service (mysqld daemon crash) in some cases.

Note: The impact of this flaw is further mitigated by the requirement only privileged user can run the BINLOG statement.

A denial of service was found in the way MySQL processed creation of temporary tables, when the InnoDB storage engine was used. A remote authenticated MySQL user could use this flaw to cause mysqld daemon abort (assertion failure).

Note: This issue only causes a temporary denial of service, as the mysql daemon shipped with Red Hat Enterprise Linux 5 will be automatically restarted after the abort.

A denial of service flaw was found in the way MySQL processed joins queries, which involved a table with unique SET column. A remote MySQL user could use this flaw to cause mysqld daemon crash.

MySQL 5.1.x before 5.1.63 and 5.5.x before 5.5.24 allows remote authenticated users to cause a denial of service (mysqld crash) via vectors related to incorrect calculation and a sort order index.

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.

Buffer overflow in yaSSL, as used in MySQL 5.1.x before 5.1.68 and 5.5.x before 5.5.30, has unspecified impact and attack vectors, a different vulnerability than CVE-2012-0553.
