Package        : mysql
Vulnerability  : insecure temporary file creation
Problem-Type   : local
Debian-specific: no
CVE IDs        : CAN-2004-0381 CAN-2004-0388
Bugtraq ID     : 9976

Two vulnerabilities have been discovered in mysql, a common database
system.  Two scripts contained in the package don't create temporary
files in a secure fashion.  This could allow a local attacker to
overwrite files with the privileges of the user invoking the MySQL
server, which is often the root user.  The Common Vulnerabilities and
Exposures identifies the following problems:

CAN-2004-0381

    The script mysqlbug in MySQL allows local users to overwrite
    arbitrary files via a symlink attack.

CAN-2004-0388

    The script mysqld_multi in MySQL allows local users to overwrite
    arbitrary files via a symlink attack.

For the stable distribution (woody) these problems have been fixed in
version 3.23.49-8.6.

For the unstable distribution (sid) these problems will be fixed in
version 4.0.18-6 of mysql-dfsg.

We recommend that you upgrade your mysql, mysql-dfsg and related
packages.


Upgrade Instructions
- --------------------

wget url
        will fetch the file for you
dpkg -i file.deb
        will install the referenced file.

If you are using the apt-get package manager, use the line for
sources.list as given below:

apt-get update
        will update the internal database
apt-get upgrade
        will install corrected packages

You may use an automated update by adding the resources from the
footer to the proper configuration.

Debian: mysql Insecure temporary file vulnerabilities

April 14, 2004
Two scripts contained in the package don't create temporary files in a secure fashion, which could lead to a root exploit.

Summary

Two vulnerabilities have been discovered in mysql, a common database
system. Two scripts contained in the package don't create temporary
files in a secure fashion. This could allow a local attacker to
overwrite files with the privileges of the user invoking the MySQL

For the stable distribution (woody) these problems have been fixed in
version 3.23.49-8.6.

For the unstable distribution (sid) these problems will be fixed in
