"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 :

  - 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

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."
