MySQL: Denial of service

MySQL: Denial of service An authenticated user can crash MySQL through invalid parameters to the date_format function. mysql 2006-08-06 2006-08-07 142429 remote 4.1.21 4.1.0 4.1.21

MySQL is a popular multi-threaded, multi-user SQL server.

Jean-David Maillefer discovered a format string vulnerability in time.cc where MySQL fails to properly handle specially formatted user input to the date_format function.

By specifying a format string as the first parameter to the date_format function, an authenticated attacker could cause MySQL to crash, resulting in a Denial of Service.

There is no known workaround at this time.

All MySQL users should upgrade to the latest version:


    # emerge --sync
    # emerge --ask --verbose --oneshot ">=dev-db/mysql-4.1.21"
