# Bug 32091: Security breach via directory changes
|
|
#
|
|
# The below test shows that a pre-existing table mysqltest2.t1 cannot be
|
|
# replaced by a user with no rights in 'mysqltest2'. The altered table
|
|
# test.t1 will be altered (remove partitioning) into the test directory
|
|
# and having its partitions removed from the mysqltest2 directory.
|
|
# (the partitions data files are named <tablename>#P#<partname>.MYD
|
|
# and will not collide with a non partitioned table's data files.)
|
|
# NOTE: the privileges on files and directories are the same for all
|
|
# database users in mysqld, though mysqld enforces privileges on
|
|
# the database and table levels which in turn maps to directories and
|
|
# files, but not the other way around (any db-user can use any
|
|
# directory or file that the mysqld-process can use, via DATA/INDEX DIR)
|
|
# this is the security flaw that was used in bug#32091 and bug#32111
|
