patches for easier mirroring, to eliminate a special copy, to make www.freebsd.org/security a full copy of security.freebsd.org and be eventually be the same. For now files are just sitting there. The symlinks are missing. Discussed on: www (repository location) Discussed with: simon (so)

FreeBSD-SA-01:16 Security Advisory

Topic: mysql may allow remote users to gain increased
|
|
privileges
|
|
|
|
Category: ports

Vendor status: Updated version released
|
|
FreeBSD only: NO

|
|
|
I. Background
|
|
|
|
mysql is a high-performance database server.
|
|
|
|
II. Problem Description
|
|
|
|
The mysql323-server port, versions prior to 3.23.22, and all
|
|
mysql322-server ports contain remote vulerabilities. Due to a buffer
|
|
overflow, a malicious remote user can cause a denial-of-service by
|
|
crashing the database. Additionally, the attacker may be able to gain
|
|
the privileges of the mysqld user, allowing access to all databases
|
|
and the ability to leverage other local attacks as the mysqld user.
|
|
In order to accomplish this, the attacker must have a valid mysql
|
|
account.
|
|
|
|
The mysql322-server and mysql323-server ports are not installed by
|
|
default, nor are they "part of FreeBSD" as such: they are part of the
|
|
FreeBSD ports collection, which contains over 4500 third-party
|
|
applications in a ready-to-install format. The ports collections
|
|
shipped with FreeBSD 3.5.1 and 4.2 contain this problem since it was
|
|
discovered after the releases.
|
|
|
|
FreeBSD makes no claim about the security of these third-party
|
|
applications, although an effort is underway to provide a security
|
|
audit of the most security-critical ports.
|
|
|
|
III. Impact
|
|
|
|
Malicious remote mysql users may cause a denial-of-service and
|
|
potentially gain access as the mysqld user, allowing access to all
|
|
databases on the mysql server and the ability to leverage other local
|
|
attacks as the mysqld user.
|
|
|
|
If you have not chosen to install the mysql322-server or
|
|
mysql323-server ports/packages, then your system is not vulnerable to
|
|
this problem.
|
|
|
|
IV. Workaround
|
|
|
|
Deinstall the mysql322-server or mysql323-server port/package, if you
|
|
have installed it.
|
|
|
|
V. Solution
|
|
|
|
Note: the mysql322-server port has been removed since mysql 3.23 is
|
|
now the stable mysql branch. People using older mysql322-server
|
|
ports/packages are urged to update to the mysql323-server
|
|
port/package.
|
|
|
|
One of the following:
|
|
|
|
1) Upgrade your entire ports collection and rebuild the
|
|
mysql323-server port.
|
|
|
|
2) Deinstall the old package and install a new package dated after the
|
|
correction date, obtained from:
|
|
|
|
[i386]
|
|
ftp://ftp.FreeBSD.org/pub/FreeBSD/ports/i386/packages-3-stable/databases/mysql-3.23.32.tgz
|
|
ftp://ftp.FreeBSD.org/pub/FreeBSD/ports/i386/packages-4-stable/databases/mysql-3.23.32.tgz
|
|
ftp://ftp.FreeBSD.org/pub/FreeBSD/ports/i386/packages-5-current/databases/mysql-3.23.32.tgz
|
|
|
|
[alpha]
|
|
Packages are not automatically generated for the alpha architecture at
|
|
this time due to lack of build resources.
|
|
|
|
3) download a new port skeleton for the mysql323-server port from:
|
|
|
|
http://www.freebsd.org/ports/
|
|
|
|
and use it to rebuild the port.
|
|
|
|
4) Use the portcheckout utility to automate option (3) above. The
|
|
portcheckout port is available in /usr/ports/devel/portcheckout or the
|
|
package can be obtained from:
|
|
|
|
ftp://ftp.FreeBSD.org/pub/FreeBSD/ports/i386/packages-3-stable/devel/portcheckout-2.0.tgz
|
|
ftp://ftp.FreeBSD.org/pub/FreeBSD/ports/i386/packages-4-stable/devel/portcheckout-2.0.tgz
|
|
ftp://ftp.FreeBSD.org/pub/FreeBSD/ports/alpha/packages-4-stable/devel/portcheckout-2.0.tgz
|
|
ftp://ftp.FreeBSD.org/pub/FreeBSD/ports/i386/packages-5-current/devel/portcheckout-2.0.tgz
|
