OpenPKG Specific: no
Affected Releases: Affected Packages: Corrected Packages:
OpenPKG CURRENT <= mysql-3.23.54a-20030116 >= mysql-3.23.55-20030124

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
