Description

MySQL before 5.1.48 allows remote authenticated users with alter database privileges to cause a denial of service (server crash and database loss) via an ALTER DATABASE command with a #mysql50# string followed by a . (dot), .. (dot dot), ../ (dot dot slash) or similar sequence, and an UPGRADE DATA DIRECTORY NAME command, which causes MySQL to move certain directories to the server data directory.

Solution(s)

  • mysql-upgrade-5_1_48
