## Description

Multiple format string vulnerabilities in the dispatch\_command function in
libmysqld/sql\_parse.cc in mysqld in MySQL 4.0.0 through 5.0.83 allow remote
authenticated users to cause a denial of service (daemon crash) and
possibly have unspecified other impact via format string specifiers in a
database name in a (1) COM\_CREATE\_DB or (2) COM\_DROP\_DB request. NOTE:
some of these details are obtained from third party information.
