______________________________________________________________________________
1) problem description, brief discussion, solution, upgrade information
Stefan Esser from e-matters reported various bugs in MySQL. Within the
MySQL server the password checking and a signedness issue has been fixed.
These could lead to a remote compromise of the system running an unpatched
MySQL server. In order to exploit this bug, the remote attacker needs a
valid MySQL account.
Further, a buffer overflow in the mysqlclient library has been reported
and fixed. Applications using this library (as commonly used from within
PHP scripts) are vulnerable to this attack and could also be compromised
by remote attackers.
Since there is no workaround possible except shutting down the MySQL
server, we strongly recommend an update.
Please download the update package for your distribution and verify its
integrity by the methods listed in section 3) of this announcement.
Then, install the package using the command "rpm -Fhv file.rpm" to apply
the update.
Our maintenance customers are being notified individually. The packages
are being offered to install from the maintenance web.
To be sure the update takes effect you have to restart the MySQL server
by executing the following command as root:
/etc/rc.d/mysql restart
If you run applications which utilize the mysqlclient library (i.e. software
that accesses a MySQL database server) make sure you restart them again to
force the use of the patched libraries.
We thank MySQL Product and Release Engineer Lenz Grimmer as well as
e-matters Stefan Esser who discovered the bugs for their committment to
security matters and the communication of them.

2) Pending vulnerabilities in SuSE Distributions and Workarounds:
- grub
The grub boot manager allows users with physical access to the
terminal to circumvent the password protection from grub. Fixed
packages will soon be available.
______________________________________________________________________________
3) standard appendix: authenticity verification, additional information
- Package authenticity verification:
SuSE update packages are available on many mirror ftp servers all over
the world. While this service is being considered valuable and important
to the free and open source software community, many users wish to be
sure about the origin of the package and its content before installing
the package. There are two verification methods that can be used
independently from each other to prove the authenticity of a downloaded
file or rpm package:
1) md5sums as provided in the (cryptographically signed) announcement.
2) using the internal gpg signatures of the rpm package.
1) execute the command
md5sum <name-of-the-file.rpm>
after you downloaded the file from a SuSE ftp server or its mirrors.
Then, compare the resulting md5sum with the one that is listed in the
announcement. Since the announcement containing the checksums is
cryptographically signed (usually using the key [email protected]),
the checksums show proof of the authenticity of the package.
We disrecommend to subscribe to security lists which cause the
email message containing the announcement to be modified so that
the signature does not match after transport through the mailing
list software.
Downsides: You must be able to verify the authenticity of the
announcement in the first place. If RPM packages are being rebuilt
and a new version of a package is published on the ftp server, all
md5 sums for the files are useless.
2) rpm package signatures provide an easy way to verify the authenticity
of an rpm package. Use the command
rpm -v --checksig <file.rpm>
to verify the signature of the package, where <file.rpm> is the
filename of the rpm package that you have downloaded. Of course,
package authenticity verification can only target an un-installed rpm
package file.
Prerequisites:
a) gpg is installed
b) The package is signed using a certain key. The public part of this
key must be installed by the gpg program in the directory
~/.gnupg/ under the user's home directory who performs the
signature verification (usually root). You can import the key
that is used by SuSE in rpm packages for SuSE Linux by saving
this announcement to a file ("announcement.txt") and
running the command (do "su -" to be root):
gpg --batch; gpg < announcement.txt | gpg --import
SuSE Linux distributions version 7.1 and thereafter install the
key "[email protected]" upon installation or upgrade, provided that
the package gpg is installed. The file containing the public key
is placed at the top-level directory of the first CD (pubring.gpg)
and at ftp://ftp.suse.com/pub/suse/pubring.gpg-build.suse.de .
