Fixed buffer overflow in password handling which could
potentially be exploited by MySQL users with
ALTER
privilege on the
mysql.user
table to execute random code
or to gain shell access with the UID of the mysqld process
(thanks to Jedi/Sector One for spotting and reporting this
bug).
mysqldump
now correctly quotes all
identifiers when communicating with the server. This assures
that during the dump process, mysqldump
will never send queries to the server that result in a
syntax error. This problem is
not related to the
mysqldump
program's output, which was not
changed. (Bug#1148)
Fixed table/column grant handling - proper sort order (from most specific to less specific, see Secção 4.3.10, “Controle de Acesso, Estágio 2: Verificação da Requisição”) was not honored. (Bug#928)
Fixed overflow bug in MyISAM
and
ISAM
when a row is updated in a table
with a large number of columns and at least one
BLOB/TEXT
column.
Fixed MySQL so that field length (in C API) for the second
column in SHOW CREATE TABLE
is always
larger than the data length. The only known application that
was affected by the old behaviour was Borland dbExpress,
which truncated the output from the command. (Bug#1064)
Fixed ISAM
bug in
MAX()
optimization.
Fixed Unknown error
when doing
ORDER BY
on reference table which was
used with NULL
value on NOT
NULL
column. (Bug#479)
