> DESCRIPTION:
> Stefano Di Paola has reported some vulnerabilities in MySQL, which
> can be exploited by malicious users to disclose potentially sensitive
> information 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.
