• A vulnerability was reported in MySQL. A remote authenticated user can cause denial of service conditions.
  
  This issue affects versions prior to MySQL 5.1.48. 
  
  A remote authenticated user can send a specially crafted ALTER DATABASE command to cause the target server to move a data directory into a new subdirectory, causing the data directory to become unusable.
  
  A demonstration exploit request is provided [where "<special>" is "." or ".." or is a sequence that begins with "./" or "../"]:
  
  ALTER DATABASE `#mysql50#<special>` UPGRADE DATA DIRECTORY NAME
