Description:
Some vulnerabilities have been reported in MySQL, which can be exploited by malicious users to disclose potentially sensitive information, cause a DoS (Denial of Service) and compromise a vulnerable system.
1) An error within the code that generates an error response to an invalid COM_TABLE_DUMP packet can be exploited by an authenticated client to disclosure certain memory content of the server process.
The vulnerability has been reported in version 4.0.26, 4.1.18, and 5.0.20. Prior versions may also be affected.
2) A boundary error within the handling of specially crafted invalid COM_TABLE_DUMP packets can be exploited by an authenticated client to cause a buffer overflow and allows arbitrary code execution.
The vulnerability has been reported in version 5.0.20. Prior versions may also be affected.
3) An error within the handling of malformed login packets can be exploited to disclosure certain memory content of the server process in the error messages.
The vulnerability has been reported in version 4.0.26, 4.1.18, and 5.0.20. Prior versions may also be affected.
4) An error exists within the handling of certain queries that contain the "STR_TO_DATE(1,NULL)" clause. This can be exploited by malicious users to cause the "mysqld" process to crash.
5) An error within the handling of invalid arguments to "DATE_FORMAT()" can be exploited by malicious users to crash the service.
The vulnerability has been reported in versions 4.1.17, 5.0.18, and 5.1.5. Prior versions may also be affected.
