    Package: mysql
    Vulnerability: arbitrary code execution
    OpenPKG Specific: no

    Affected Releases: Affected Packages: Corrected Packages:
    OpenPKG CURRENT <= mysql-4.0.14-20030904 >= mysql-4.0.15-20030910
    OpenPKG 1.3 <= mysql-4.0.14-1.3.1 >= mysql-4.0.14-1.3.2
    OpenPKG 1.2 <= mysql-3.23.54a-1.2.3 >= mysql-3.23.54a-1.2.4

    Dependent Packages: none

    Description:
      Frank Denis reported a vulnerability [0] in MySQL [1] affecting MySQL3
      versions 3.0.57 and earlier and MySQL4 versions 4.0.14 and earlier.
      Passwords of MySQL users are stored in the "Password" field of the
      "User" table, part of the "mysql" database. The passwords are hashed
      and stored as a 16 characters long hexadecimal value. Unfortunately, a
      function involved in password checking misses correct bounds checking.
      By filling a "Password" field a value wider than 16 characters, a
      buffer overflow will occur. The Common Vulnerabilities and Exposures
      (CVE) project assigned the id CAN-2003-0780 [2] to the problem.

      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). [3][4]

    Solution:
      Select the updated source RPM appropriate for your OpenPKG release
      [5][6], fetch it from the OpenPKG FTP service [7][8] or a mirror
      location, verify its integrity [9], build a corresponding binary RPM
      from it [3] and update your OpenPKG installation by applying the
      binary RPM [4]. For the current release OpenPKG 1.3, perform the
      following operations to permanently fix the security problem (for
      other releases adjust accordingly).

      $ ftp ftp.openpkg.org
      ftp> bin
      ftp> cd release/1.3/UPD
      ftp> get mysql-4.0.14-1.3.2.src.rpm
      ftp> bye
      $ <prefix>/bin/rpm -v --checksig mysql-4.0.14-1.3.2.src.rpm
      $ <prefix>/bin/rpm --rebuild mysql-4.0.14-1.3.2.src.rpm
      $ su -
      # <prefix>/bin/rpm -Fvh <prefix>/RPM/PKG/mysql-4.0.14-1.3.2.*.rpm
