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
