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. There exists an information disclosure vulnerability in MySQL database. The vulnerability is due to a flaw in the server component responsible for the login handshake procedure and allows an attacker with anonymous access to the database to read sensitive data stored in the memory of the server. The attacker then may use the acquired information to compromise the server or to facilitate other attack attempts. After an attack attempt exploiting this vulnerability, the information in the memory may be disclosed to the attacker. At the same time, the server will continue operating normally in almost all attack scenarios, as the affected process is not likely to perform any more illegal operations.
