Synopsis

A Denial of Service vulnerability and a table structure information leakage vulnerability were found in MySQL.

Background

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

Affected packages

     Package       /  Vulnerable  /                         Unaffected
    -------------------------------------------------------------------
  1  dev-db/mysql      < 5.0.44                              >= 5.0.44

Impact

A remote unauthenticated attacker could use the first vulnerability to make the server crash. The second vulnerability can be used by authenticated users to obtain information on tables they are not normally able to access.

Workaround

There is no known workaround at this time.

Resolution

All MySQL users should upgrade to the latest version:

    # emerge --sync
    # emerge --ask --oneshot --verbose ">=dev-db/mysql-5.0.44"
