Overview
A remotely exploitable stack buffer overflow exists in the Samba server daemon (smbd).
Description
Versions 2.2.2 through 2.2.6 of Samba contain a remotely exploitable stack buffer overflow. The Samba Team describes Samba as follows:
The Samba software suite is a collection of programs that implements the Server Message Block (commonly abbreviated as SMB) protocol for UNIX systems. This protocol is sometimes also referred to as the Common Internet File System (CIFS), LanManager or NetBIOS protocol.
The Samba Team describes the vulnerability as follows:
There was a bug in the length checking for encrypted password change requests from clients. A client could potentially send an encrypted password, which, when decrypted with the old hashed password could be used as a buffer overrun attack on the stack of smbd. The attach would have to be crafted such that converting a DOS codepage string to little endian UCS2 unicode would translate into an executable block of code.
Impact
A remote attacker can execute arbitrary code with superuser privileges or can cause smbd to crash.
Solution
Apply a patch from your vendor.

CONECTIVA LINUX SECURITY ANNOUNCEMENT
PACKAGE : samba
SUMMARY : Buffer overflow vulnerability
DATE : 2002-11-22 16:13:00
ID : CLA-2002:550
RELEVANT
RELEASES : 6.0, 7.0, 8
- -------------------------------------------------------------------------
DESCRIPTION
Samba is a server that provides SMB services such as file and printer
sharing for other SMB clients, such as Windows®.
Steve Langasek and Eloy Paris discovered a vulnerability in Samba
versions 2.2.2 to 2.2.6 which may allow a remote attacker to execute
arbitrary code in the server context. The vulnerability, which is a
buffer overflow in a function used to decrypt hashed passwords, can
be exploited by an attacker when authenticating a valid account in
the samba server. In order to sucessfully run arbitrary code, the
overflow must be crafted such that converting a DOS codepage string
to little endian UCS2 unicode translates into an executable block of
code.
This update also adds other fixes for potential buffer overflows from
samba 2.2.7 that are not part of the standard patch supplied by the
samba authors in their announcement[1]. The samba package distributed
in Conectiva Linux 6.0 (samba-2.0.9) is not vulnerable to the
announced buffer overflow, but it is being upgraded with these
aditional fixes.
`
SOLUTION All samba users should upgrade their packages immediately. This update will automatically restart the samba service if it is already running.

Package : samba Problem type : remote exploit Debian-specific: no
Steve Langasek found an exploitable bug in the password handling code in samba: when converting from DOS code-page to little endian UCS2 unicode a buffer length was not checked and a buffer could be overflowed. There is no known exploit for this, but an upgrade is strongly recommended.
This problem has been fixed in version 2.2.3a-12 of the Debian samba packages and upstream version 2.2.7.

GENTOO LINUX SECURITY ANNOUNCEMENT 200211-007
PACKAGE : samba
SUMMARY?: remote root access
DATE ?? : 2002-11-21 09:11 UTC
EXPLOIT : remote
- - --------------------------------------------------------------------
- From 2.2.7 release notes:
There was a bug in the length checking for encrypted password change
requests from clients. A client could potentially send an encrypted
password, which, when decrypted with the old hashed password could be
used as a buffer overrun attack on the stack of smbd. The attach would
have to be crafted such that converting a DOS codepage string to little
endian UCS2 unicode would translate into an executable block of code.
Read the full release notes at
<http://se.samba.org/samba/whatsnew/samba-2.2.7.html>
SOLUTION
It is recommended that all Gentoo Linux users who are running
net-fs/samba-2.2.5-r1 and earlier update their systems as follows:
emerge rsync
emerge samba
emerge clean

SSRT2434 Security vulnerability with HP-UX Visualize Conference
NOTICE: There are no restrictions for distribution of this Bulletin
provided that it remains complete and intact.
The information in the following Security Bulletin should be
acted upon as soon as possible. Hewlett-Packard Company will
not be liable for any consequences to any customer resulting
from customer’s failure to fully implement instructions in this
Security Bulletin as soon as possible.
------------------------------------------------------------------
PROBLEM: The installation of HP-UX Visualize Conference leaves
certain directories with insecure permissions.
IMPACT: Potential increase in privileges, unauthorized access.
PLATFORM: HP 9000 Series 700 and 800, HP-UX 11.00 and 11.11 systems
which have ever installed HP-UX Visualize Conference
version B.11.00.11.
SOLUTION: Change the insecure directory permissions.
MANUAL ACTIONS: Yes - NonUpdate
Change ownership and permissions as follows:
/etc/dt 755 bin/bin
/etc/dt/appconfig 755 root/sys
/etc/dt/appconfig/icons 755 root/sys
/etc/dt/appconfig/icons/C 755 root/sys
/etc/dt/appconfig/types 755 root/sys
/etc/dt/appconfig/types/C 755 root/sys
AVAILABILITY: This bulletin will be revised when a product
update is available.
A. Background
If HP-UX Visualize Conference version B.11.00.11 has ever been
installed on an 11.00 or 11.11 system the permissions of
certain directories may be insecure.
The installation of HP-UX Visualize Conference may leave
certain directories with insecure permissions. The
vulnerability is not with the HP-UX Visualize Conference
product itself, but rather with the state of the directory permissions after HP-UX Visualize Conference has been installed.
The vulnerability remains even after HP-UX Visualize Conference
is removed.
The problem arises if the directories do not exist at the time
HP-UX Visualize Conference version B.11.00.11 is installed.
Therefore not all systems with HP-UX Visualize Conference
version B.11.00.11 are vulnerable. Also once the directory
permissions are corrected a subsequent reinstallation of
HP-UX Visualize Conference version B.11.00.11 will not alter
the permissions.
B. Recommended solution
Change the insecure directory permissions using the following
procedure or the equivalent:
As root create a script “chown_chmod”:
#!/sbin/sh
chown_chmod root:sys 755 file
chown $1 $3
chmod $2 $3
Then:
chown_chmod bin:bin 755 /etc/dt
chown_chmod root:sys 755 /etc/dt/appconfig
chown_chmod root:sys 755 /etc/dt/appconfig/icons
chown_chmod root:sys 755 /etc/dt/appconfig/icons/C
chown_chmod root:sys 755 /etc/dt/appconfig/types
chown_chmod root:sys 755 /etc/dt/appconfig/types/C

Problem Description:
A vulnerability in samba versions 2.2.2 through 2.2.6 was discovered
by the Debian samba maintainers. A bug in the length checking for
encrypted password change requests from clients could be exploited
using a buffer overrun attack on the smbd stack. This attack would
have to crafted in such a way that converting a DOS codepage string to
little endian UCS2 unicode would translate into an executable block of
code.
This vulnerability has been fixed in samba version 2.2.7, and the
updated packages have had a patch applied to fix the problem.

`Synopsis: New samba packages available to fix potential security vulnerability
Advisory ID: RHSA-2002:266-05
Issue date: 2002-11-22
Updated on: 2002-11-21
Product: Red Hat Linux
Keywords: samba security encrypted password change
Cross references:
Obsoletes:
1. Topic:
New samba packages are available that fix a security vulnerability present
in samba versions 2.2.2 through 2.2.6. A potential attacker could gain
root access on the target machine. It is strongly encouraged that all Samba
users update to the fixed packages.
As of this time, there are no known exploits for this vulnerability.
2. Relevant releases/architectures:
Red Hat Linux 7.3 - i386
Red Hat Linux 8.0 - i386
3. Problem description:
There was a bug in the length checking for encrypted password change
requests from clients. A client could potentially send an encrypted
password, which, when decrypted with the old hashed password, could be
used as a buffer overrun attack on smbd’s stack. The attack would
have to be crafted such that converting a DOS codepage string to little
endian UCS2 unicode would translate into an executable block of code.
Thanks to the Debian Samba maintainers for discovering this issue, and to
the Samba team for providing the fix (and the problem description text above.)
4. Solution:
Before applying this update, make sure all previously released errata
relevant to your system have been applied.
To update all RPMs for your particular architecture, run:
rpm -Fvh [filenames]
where [filenames] is a list of the RPMs you wish to upgrade. Only those
RPMs which are currently installed will be updated. Those RPMs which are
not installed but included in the list will not be updated. Note that you
can also use wildcards (*.rpm) if your current directory only contains the
desired RPMs.
Please note that this update is also available via Red Hat Network. Many
people find this an easier way to apply updates. To use Red Hat Network,
launch the Red Hat Update Agent with the following command:
up2date
This will start an interactive process that will result in the appropriate
RPMs being upgraded on your system.
5. RPMs required:

`Title : Samba Security Vulnerability
Number : 20021204-01-I
Date : December 5, 2002
Reference: CVE CAN-2002-1318
Reference: SGI BUG 874162
Fixed in : Samba v2.2.7
- -----------------------
- — Issue Specifics —
It’s been reported that versions of Samba prior to 2.2.7 have a security
vulnerability that could potentially allow an attacker to gain root access
on the target machine. The word “potentially” is used because there
is no known exploit of this bug. SGI has not found one, nor has the Samba
group found one. Nevertheless, the vulnerability is considered serious.
See <http://www.samba.org/samba/whatsnew/samba-2.2.7.html> for additional
details.
This vulnerability was assigned the following CVE candidate:
<http://cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2002-1318>
SGI has investigated the issue and recommends the following steps for
neutralizing the exposure. It is HIGHLY RECOMMENDED that these measures be
implemented on ALL vulnerable SGI systems.
These issues have been corrected in Samba version 2.2.7.
`
`- --------------
- — Impact —
Samba is an optional product, and is not installed by default on IRIX 6.5
systems.
To determine the version of IRIX you are running, execute the following
command:
# /bin/uname -R
That will return a result similar to the following:
# 6.5 6.5.16f
The first number (“6.5”) is the release name, the second (“6.5.16f” in this
case) is the extended release name. The extended release name is the
“version” we refer to throughout this document.
To see if samba is installed, execute the following command:
% versions samba_irix
I = Installed, R = Removed
Name Date Description
I samba_irix 07/02/2002 Samba 2.2.4 for IRIX
I samba_irix.man 07/02/2002 Samba Online Documentation
I samba_irix.man.doc 07/02/2002 Samba 2.2.4 Documentation
I samba_irix.man.manpages 07/02/2002 Samba 2.2.4 Man Page
I samba_irix.man.relnotes 07/02/2002 Samba 2.2.4 Release Notes
I samba_irix.src 07/02/2002 Samba Source Code
I samba_irix.src.samba 07/02/2002 Samba 2.2.4 Source Code
I samba_irix.sw 07/02/2002 Samba Execution Environment
I samba_irix.sw.base 07/02/2002 Samba 2.2.4 Execution Environment
If the result is similar to the above and the version shown is less than
2.2.7, then the system is vulnerable.
- ----------------------------
- — Temporary Workaround —
There is no effective workaround available for these problems if Samba is
required. SGI recommends upgrading to Samba version 2.2.7.
`
`- ----------------
- — Solution —
SGI has provided an instable version of Samba for this vulnerability. Our
recommendation is to upgrade to Samba version 2.2.7.
Samba 2.2.7 can be downloaded from <http://www.samba.org/> or
<http://freeware.sgi.com/>
For customers who have purchased the SGI supported version of Samba,
please contact your SGI Support Representative and request part
number 812-0893-008 – Samba 2.2.7 for IRIX on CD.

Slackware __ Affected
Updated: December 13, 2002
Status
Affected
Vendor Statement
New Samba packages are available for Slackware 8.1 and -current to fix a security problem and provide other bugfixes and improvements.
Here are the details from the Slackware 8.1 ChangeLog:
`----------------------------
Wed Nov 20 16:51:23 PST 2002
patches/packages/samba-2.2.7-i386-1.tgz: Upgraded to samba-2.2.7.
Some details (based on the WHATSNEW.txt file included in samba-2.2.7):
This fixes a security hole discovered in versions 2.2.2 through 2.2.6 of
Samba that could potentially allow an attacker to gain root access
on the target machine. The word “potentially” is used because there
is no known exploit of this bug, and the Samba Team has not been able to
craft one ourselves. However, the seriousness of the problem warrants
this immediate 2.2.7 release. There was a bug in the length checking for
encrypted password change requests from clients. A client could potentially
send an encrypted password, which, when decrypted with the old hashed
password could be used as a buffer overrun attack on the stack of smbd. The
attack would have to be crafted such that converting a DOS codepage string
to little endian UCS2 unicode would translate into an executable block of
code. Thanks to Steve Langasek <[email protected]> and Eloy Paris
<[email protected]> for bringing this vulnerability to our notice.

that accepts user input and may write up to 127 bytes past the end of
the buffer allocated with static length, leaving enough room for
an exploit. The resulting vulnerability can be exploited locally
in applications using the pam_smbpass Pluggable Authentication Module
(PAM). It may be possible to exploit this vulnerability remotely,
causing the running smbd to crash or even to execute arbitrary code.
Enterprise Server. SuSE Linux products do not have the samba and
samba-client packages installed by default.
The samba packages in SuSE Linux version 7.1 and before are not affected
by this vulnerability.
For the bug to be exploited, your system has to be running the smbd
samba server, or an administrator must have (manually) changed the
configuration of the PAM authentification subsystem to enable the use
of the pam_smbpass module. The samba server process(es) are not activated
automatically after installation (of the package).
subpackages: samba and smbclnt up to and including SuSE Linux 7.2, on
SuSE Linux 7.3 and newer the package names are samba and samba-client.
To completely remove the vulnerability, you should update all of the
installed packages.
in particular to Steve Langasek and Volker Lendecke who provided the
patches and communicated them to the vendors. Please know that the
samba team will release the new version 2.2.7 of the samba software to
address the security fix at the same time as this announcement gets
published. More information about samba (and the security fix) is
available at<http://www.samba.org>.

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.
==============================
After successfully installing the update packages, you should restart
the samba server process(es) to make the changes in the system effective.
If you do not have a samba server running on your system, no further
action is required. If you have a samba server running, please run the
following command as root:
rcsmb restart # SuSE Linux, all versions
rcnmb restart # only on SuSE Linux 8.1

2) Pending vulnerabilities in SuSE Distributions and Workarounds:
- 7.0 update trees We will move the SuSE Linux 7.0 update tree structure to the /pub/suse/discontinued/ tree shortly, following the announcement about discontinued products on Tue, 29 Oct 2002.
______________________________________________________________________________
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:
- md5sums as provided in the (cryptographically signed) announcement.
- using the internal gpg signatures of the rpm package.
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.
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>.

`OpenPKG Security Advisory The OpenPKG Project
<http://www.openpkg.org/security.html> <http://www.openpkg.org>
[email protected] [email protected]
OpenPKG-SA-2002.012 29-Nov-2002
Package: samba
Vulnerability: code execution, root exploit
OpenPKG Specific: no
Dependent Packages: none
Affected Releases: Affected Packages: Corrected Packages:
OpenPKG 1.0 <= samba-2.2.2-1.0.0 >= samba-2.2.2-1.0.1
OpenPKG 1.1 <= samba-2.2.5-1.1.0 >= samba-2.2.5-1.1.1
OpenPKG CURRENT <= samba-2.2.6-20021017 >= samba-2.2.7-20021120
Description:
A vulnerability in Samba [0] versions 2.2.2 through 2.2.6 was
discovered by the Debian Samba maintainers [1]. A bug in the
length checking for encrypted password change requests from clients
could be exploited using a buffer overrun attack on the smbd(8)
stack. This attack would have to be crafted in such a way that
converting a DOS codepage string to little endian UCS2 unicode
would translate into an executable block of code.
Check whether you are affected by running “<prefix>/bin/rpm -q
samba”. If you have an affected version of the samba package (see
above), please upgrade it according to the solution below.
Solution:
Update existing packages to newly patched versions of Samba. Select the
updated source RPM appropriate for your OpenPKG release [2][3][4], and
fetch it from the OpenPKG FTP service or a mirror location. Verify its
integrity [5], build a corresponding binary RPM from it and update your
OpenPKG installation by applying the binary RPM [6]. For the latest
OpenPKG 1.1 release, perform the following operations to permanently fix
the security problem (for other releases adjust accordingly).
$ ftp ftp.openpkg.org
ftp> bin
ftp> cd release/1.1/UPD
ftp> get samba-2.2.5-1.1.1.src.rpm
ftp> bye
$ <prefix>/bin/rpm -v --checksig samba-2.2.5-1.1.1.src.rpm
$ <prefix>/bin/rpm --rebuild samba-2.2.5-1.1.1.src.rpm
$ su -

Trustix Secure Linux __ Affected
Updated: December 13, 2002
Status
Affected
Vendor Statement
-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1
- -------------------------------------------------------------------------- Trustix Secure Linux Security Advisory #2002-0080
Package name: samba Summary: Remote hole Date: 2002-11-21 Affected versions: TSL 1.5
- -------------------------------------------------------------------------- Package description: Samba provides an SMB server which can be used to provide network services to SMB (sometimes called "Lan Manager") clients, including various versions of MS Windows, OS/2, and other Linux machines. Samba uses NetBIOS over TCP/IP (NetBT) protocols and does NOT need NetBEUI (Microsoft Raw NetBIOS frame) protocol.
Problem description: From the Samba 2.2.7 release notes:
There was a bug in the length checking for encrypted password change requests from clients. A client could potentially send an encrypted password, which, when decrypted with the old hashed password could be used as a buffer overrun attack on the stack of smbd. The attach would have to be crafted such that converting a DOS codepage string to little endian UCS2 unicode would translate into an executable block of code.
All versions of Samba between 2.2.2 to 2.2.6 inclusive are vulnerable to this problem. This version of Samba 2.2.7 contains a fix for this problem.
Action: We recommend that all systems with this package installed be upgraded. Please note that if you do not need the functionality provided by this package, you may want to remove it from your system.
Location: All TSL updates are available from <URI:``<http://www.trustix.net/pub/Trustix/updates/>``> <URI:``<ftp://ftp.trustix.net/pub/Trustix/updates/>``>
