    Package: mysql
    Vulnerability: double free can cause denial of service
    OpenPKG Specific: no

    Affected Releases: Affected Packages: Corrected Packages:
    OpenPKG CURRENT <= mysql-3.23.54a-20030116 >= mysql-3.23.55-20030124
    OpenPKG 1.2 <= mysql-3.23.54a-1.2.0 >= mysql-3.23.54a-1.2.1
    OpenPKG 1.1 <= mysql-3.23.52-1.1.1 >= mysql-3.23.52-1.1.2

    Affected Releases: Dependent Packages: none

    Description:
      Vincent Danen of Mandrake Linux noticed that according to the change
      log [0] for MySQL release 3.23.55 [1] a vulnerbility has been fixed
      where a double-free pointer bug in mysql_change_user() handling
      enabled a specially hacked version of MySQL client to crash mysqld.
      The vendor states that one needs to successfully login to the server
      by using a valid user account to be able to exploit this bug.

      Please check whether you are affected by running "<prefix>/bin/rpm -q
      mysql". If you have the "mysql" package installed and its version is
      affected (see above), we recommend that you immediately upgrade it
      (see Solution). [2][3]

    Solution:
      Select the updated source RPM appropriate for your OpenPKG release
      [4][5], fetch it from the OpenPKG FTP service [6][7] or a mirror
      location, verify its integrity [8], build a corresponding binary RPM
      from it [2] and update your OpenPKG installation by applying the binary
      RPM [3]. For the current release OpenPKG 1.2, perform the following
      operations to permanently fix the security problem (for other releases
      adjust accordingly).

      $ ftp ftp.openpkg.org
      ftp> bin
      ftp> cd release/1.2/UPD
      ftp> get mysql-3.23.54a-1.2.1.src.rpm
      ftp> bye
      $ <prefix>/bin/rpm -v --checksig mysql-3.23.54a-1.2.1.src.rpm
      $ <prefix>/bin/rpm --rebuild mysql-3.23.54a-1.2.1.src.rpm
      $ su -
      # <prefix>/bin/rpm -Fvh <prefix>/RPM/PKG/mysql-3.23.54a-1.2.1.*.rpm
