    OpenPKG-SA-2004.014 14-Apr-2004

    Package: mysql
    Vulnerability: insecure temporary file creation
    OpenPKG Specific: no

    Affected Releases: Affected Packages: Corrected Packages:
    OpenPKG CURRENT <= mysql-4.0.18-20040214 >= mysql-4.0.18-20040414
    OpenPKG 2.0 <= mysql-4.0.18-2.0.0 >= mysql-4.0.18-2.0.1
    OpenPKG 1.3 <= mysql-4.0.14-1.3.2 >= mysql-4.0.14-1.3.3

    Dependent Packages: none

    Description:
      Shaun Colley discovered [1] that the scripts "mysqlbug" and
      "mysqld_multi" of the MySQL RDBMS [0] perform insecure creations of
      temporary files. An attacker could create symbolic links in /tmp to
      achieve the overwriting of files with the privileges of the user
      invoking the scripts. The RDBMS startup wrapper "mysqld_multi" is
      currently not used in OpenPKG, although it is contained in the
      "mysql" package. The "mysqlbug" script could be run manually by the
      administrator. The Common Vulnerabilities and Exposures (CVE) project
      assigned the ids CAN-2004-0381 [2] and CAN-2004-0388 [3] 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). [4][5]

    Solution:
      Select the updated source RPM appropriate for your OpenPKG release
      [6][7], fetch it from the OpenPKG FTP service [8][9] or a mirror
      location, verify its integrity [10], build a corresponding binary
      RPM from it [4] and update your OpenPKG installation by applying the
      binary RPM [5]. For the most recent release OpenPKG 2.0, perform the
      following operations to permanently fix the security problem (for
      other releases adjust accordingly).

      $ ftp ftp.openpkg.org
      ftp> bin
      ftp> cd release/2.0/UPD
      ftp> get mysql-4.0.18-2.0.1.src.rpm
      ftp> bye
      $ <prefix>/bin/openpkg rpm -v --checksig mysql-4.0.18-2.0.1.src.rpm
      $ <prefix>/bin/openpkg rpm --rebuild mysql-4.0.18-2.0.1.src.rpm
      $ su -
      # <prefix>/bin/openpkg rpm -Fvh <prefix>/RPM/PKG/mysql-4.0.18-2.0.1.*.rpm
