Who is Vulnerable?
Vulnerability Description	MySQL is an open-source implementation of a relational database management system. MySQL supports the SQL (Structured Query Language) database query language. The database product allows remote network connections from client applications over the proprietary MySQL network protocol. In addition to regular client/server communications, facilities also exist for master/slave server exchanges if such configurations are desirable. A stack buffer overflow vulnerability exists in the MySQL database server product. The flaw is created by improperly implemented boundary checks on incoming user input. An authenticated attacker with limited privileges may exploit this issue to execute arbitrary code on the vulnerable host within the context of the server process. In the case where code injection was unsuccessful, the affected service will terminate. Note that on Linux and Unix-based systems, the service will be restarted immediately, whereas on Windows-based systems, this is not the case by default. Regardless, all transactions and connections present at the time of termination will be aborted. In the case where code inject and execution is successful, the behaviour of the target system will depend on the nature of the injected code. On Windows-based systems, the injected code will run in the security context of the system user, which may compromise the system. On Linux and Unix-based systems, the injected code will run with limited privileges.
