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

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
