While performing an audit of MySQL e-matters found several problems :
signed/unsigned problem in COM_TABLE_DUMP Two sizes were taken as signed integers from a request and then cast to unsigned integers without checking for negative numbers. Since the resulting numbers where used for a memcpy() operation this could lead to memory corruption.Password length handling in COM_CHANGE_USER When re-authenticating to a different user MySQL did not perform all checks that are performed on initial authentication. This created two problems :
read_rows() overflow in libmysqlclient When processing the rows returned by a SQL server there was no check for overly large rows or terminating NUL characters. This can be used to exploit SQL clients if they connect to a compromised MySQL server.read_one_row() overflow in libmysqlclient When processing a row as returned by a SQL server the returned field sizes were not verified. This can be used to exploit SQL clients if they connect to a compromised MySQL server.
For Debian GNU/Linux 3.0/woody this has been fixed in version 3.23.49-8.2 and version 3.22.32-6.3 for Debian GNU/Linux 2.2/potato.

problems :
- it allowed for single-character password brute forcing
(as was fixed in February 2000 for initial login) which
could be used by a normal user to gain root privileges
to the database
- it was possible to overflow the password buffer and
force the server to execute arbitrary code
