Overview

A function originally derived from 4.4BSD, realpath(3), contains a vulnerability that may permit a malicious user to gain root access to the server. This function was derived from the FreeBSD 3.x tree. Other applications and operating systems that use or were derived from this code base may be affected. This problem was originally reported to affect WU-FTPd. It has been discoved to affect various BSD implementations as well.

Description

Several BSD operating systems and WU-FTPd are vulnerable to an off-by-one buffer overflow vulnerability. The vulnerable code is in the realpath(3) function and exploitation may be made through the use of several commands. Details of the vulnerability related to WU-FTPd can be found in the security advisory released by isec.pl. According to their advisory:

Linux 2.2.x and some early 2.4.x kernel versions defines PATH_MAX to be
4095 characters, thus only wu-ftpd binaries compiled on 2.0.x or later 2.4.x
kernels are affected.

Upon further investigation, it has been determined that the vulnerable WU-FTPd function was derived from code in the FreeBSD 3.x tree. This code appears to have come from 4.4BSD. Therefore, other applications and operating systems that use or were derived from this code base may be affected. This problem was originally reported to affect WU-FTPd. It has been discoved to affect various BSD implementations as well.

SuSE Security Announcement

Package: wuftpd
Announcement-ID: SuSE-SA:2003:032
Date: Thursday, July 31st 2003 18:00 MEST
Affected products: 7.2, 7.3
SuSE Linux Enterprise Server 7
SuSE Linux Connectivity Server
SuSE Linux Office Server
Vulnerability Type: remote buffer overflow
Severity (1-10): 7
SuSE default package: no
Cross References: CAN-2003-0466

Content of this advisory:
1) security vulnerability resolved: wuftpd
problem description, discussion, solution and upgrade information
2) pending vulnerabilities, solutions, workarounds
3) standard appendix (further information)

______________________________________________________________________________

1) problem description, brief discussion, solution, upgrade information

Janusz Niewiadomski and Wojciech Purczynski of iSEC Security Research
have found a single byte buffer overflow in the Washington University
ftp daemon (wuftpd), a widely used ftp server for Linux-like systems.
It is yet unclear if this bug is (remotely) exploitable. Positive
exploitability may result in a remote root compromise of a system
running the wuftpd ftp daemon.

Notes:
* SuSE Linux products do not contain wuftpd any more starting with SuSE
Linux 8.0 and SuSE Linux Enterprise Server 8. The wuftpd package has
been substituted by a different server implementation of the file
transfer protocol server.
* The affected wuftpd packages in products as stated in the header of
this announcement actually ship two different wuftpd ftp daemon
versions: The older version 2.4.x that is installed as
/usr/sbin/wu.ftpd, the newer version 2.6 is installed as
/usr/sbin/wu.ftpd-2.6 . The 2.4.x version does not contain the
defective parts of the code and is therefore not vulnerable to the
weakness found.
* If you are using the wuftpd ftp daemon in version 2.4.x, you might
want to update the package anyway in order not to risk an insecure
configuration once you switch to the newer version.

There exists no workaround that can fix this vulnerability on a temporary
basis other than just using the 2.4.x version as mentioned above.
The proper fix for the weakness is to update the package using the
provided update packages.

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.

______________________________________________________________________________

2) Pending vulnerabilities in SuSE Distributions and Workarounds:

- gnats
Several security bugs were reported in gnats. The version of gnats
that comes with SuSE Linux is not vulnerable to these problems.

- kopete
Kopete is the KDE instant messenger. A bug in kopete's gpg plugin can
be abused to execute commands remotely. A fix will be available as
soon as possible.

- wget
When handling long URLs, a buffer underrun may occur in the wget
program. This underrun may be exploitable remotely. The update
packages are available now on our ftp servers.

- emacs
Due to insecure temporary file handling in the semi and wemi library
of GNU Emacs it is possible for a local attacker to overwrite
arbitrary files of the user running emacs. The fix is currently being
worked on.

- ethereal
Several remote exploitable bugs were found in the network analyzing
tool ethereal. The update packages are available on our ftp servers.


- tomcat
Wrong file permission and clear passwords in the tomcat default
installation allows local users to gain security relevant data by
reading the file /opt/jakarta/tomcat/conf/tomcat-users.xml.
Please enable password encryption and revoke the read permissions
for 'group' and 'others' by adding the following line to
/etc/permissions.local:
/opt/jakarta/tomcat/conf/tomcat-users.xml wwwrun.root 0700
and run the following command as root:
"chkstat -set /etc/permissions.local"

- heartbeat
A format string bug in heartbeat's debug code can be exploited
by a remote attacker if the debug level is high and the heartbeat
daemon in configuered in an unsecure manner. The update packages are
being tested right now.

- freeradius
A buffer overflow in the CHAP implementation of freeradius leads to a
remotely exploitable security hole which can be abused to execute
arbitrary code on the RADIUS server. The update packages are being
tested right now.

- traceroute(-nanog)
An integer overflow in traceroute-nanog can be abused to gain
access to the raw ip socket.
We are working on the fix.

- kdelibs
Due to the fact of verifying the IP address instead of the Common
Name (CN) field of the X.509 certificate the SSL implementation of
KDE 2.2 and earlier is vulnerable to a MiM attack.
Only SuSE Linux 7.3 is affected by this problem. Update packages
are available on our FTP servers.

- man
The mandb program which is part of the man package contains a
buffer overflow which allows local attackers to execute arbitrary
code as man user. New packages are already availabale on our ftp
servers.

- several minor bug fixes
There are alot more minor security updates in the queue. YOU (Yast
Online Update) will inform you when they appear. Alternatively you
may want to monitor the following website:
<http://www.suse.de/de/private/download/updates/index.html>
or:

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> .
