This allows remote attackers who have access to the 'User' table to execute arbitrary commands as mysql user. The list of affected packages is as follows: mysql, mysql-client, mysql-shared, mysql-bench, mysql-devel, mysql-Max. In this advisory the MD5 sums for the mysql, mysql-shared and mysql-devel packages are listed.

1) problem description, brief discussion, solution, upgrade information
A remotely exploitable buffer overflow within the authentication code
of MySQL has been reported. This allows remote attackers who have
access to the 'User' table to execute arbitrary commands as mysql user.
The list of affected packages is as follows:
mysql, mysql-client, mysql-shared, mysql-bench, mysql-devel, mysql-Max.
In this advisory the MD5 sums for the mysql, mysql-shared and mysql-devel
packages are listed.
To be sure the update takes effect you have to restart the MySQL server
by executing the following command as root:
/usr/sbin/rcmysql restart
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

2) Pending vulnerabilities in SuSE Distributions and Workarounds:
- OpenSSL
Critical bugs within the ASN.1 parsing routines have been reported recently.
We are currently building new packages and will notify you in a separate
advisory when the packages are 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 security@suse.de),
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 "build@suse.de" 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 .
