Bugs Fixed:
  • Due to security reasons ld_preload libraries can now only be loaded from the system directories (/usr/lib64, /usr/lib) and the MySQL installation base directory. This fix also addresses issue with where limiting didn’t work correctly for relative paths. Bug fixed #1624247.
  • Fixed possible privilege escalation that could be used when running REPAIR TABLE on a MyISAM table. Bug fixed #1624397.
  • The general query log and slow query log cannot be written to files ending in .ini and .cnf anymore. Bug fixed #1624400.
  • Implemented restrictions on symlinked files (error_log, pid_file) that can’t be used with mysqld_safe. Bug fixed #1624449.

Other bugs fixed: #1553938.
