Security Fix: Using
RENAME TABLE against a table with explicit
DATA DIRECTORY and
INDEX DIRECTORY options can be used to overwrite system table information by replacing the symbolic link points. the file to which the symlink points.
MySQL will now return an error when the file to which the symlink points already exists. (Bug #32111, CVE-2007-5969)
ALTER VIEW retained the original
DEFINER value, even when altered by another user, which could enable that user to gain the access rights of the view. Now
ALTER VIEW is permitted only to the original definer or users with the
SUPER privilege. (Bug #29908)
Security Fix: When using a
FEDERATED table, the local server could be forced to crash if the remote server returned a result with fewer columns than expected. (Bug #29801)
InnoDB had a race condition for an adaptive hash rw-lock waiting for an X-lock. This fix may also provide significant speed improvements on systems experiencing problems with contention for the adaptive hash index. (Bug #29560)
A build problem introduced in MySQL 5.0.52 was resolved: The x86 32-bit Intel icc-compiled server binary had unwanted dependences on Intel icc runtime libraries. (Bug #32514)
InnoDB does not support
SPATIAL indexes, but could crash when asked to handle one. Now an error is returned. (Bug #32125)
mysql-test-run.pl could not run mysqld with
root privileges. (Bug #30630)
