SUSE Security Announcement

Package: mailman
Announcement-ID: SUSE-SA:2005:007
Date: Monday, Feb 14th 2005 10:30 MET

CAN-2004-1143
CAN-2004-1177

Content of this advisory:
1) security vulnerability resolved:
- remote file disclosure by directory traversal
- cross site scripting
- requires additional package python-xml
2) solution/workaround
3) special instructions and notes
4) package location and checksums

______________________________________________________________________________

1) problem description, brief discussion

Mailman is a flexible mailing list management tool. It provides
mail controlled subscription front ends and also includes CGI scripts
to handle subscription, moderation and archive retrieval and other
options.

Due to incomplete input validation the "private" CGI script which
handles archive retrieval could be used to read any file on the
system, including the configuration database of the mailman lists
which include passwords in plain text. A remote attacker just needs
a valid account on one mailing list managed by this mailman instance.

This update fixes this problem and is tracked under the Mitre CVE
ID CAN-2005-0202.

Please see section (3), "special instructions and notes".

Our previous mailman update (only announced in the SUSE Summary Report)
additionally fixed the following two security problems:
- a cross site scripting problem (CAN-2004-1177)
- too weak auto generated passwords (CAN-2004-1143)

This previous security fix requires the additional "python-xml" RPM
which was not required before.

2) solution/workaround

Temporary workarounds:

- Disable execution of the CGI scripts of mailman by either moving
the scripts away, or disabling it in the web servers configuration.


- Edit the true_path function in the Mailman/Cgi/private.py script to
contain:

SLASH = '/'

def true_path(path):
"Ensure that the path is safe by removing .."
parts = [x for x in path.split(SLASH) if x not in ('.',
'..')]
return SLASH.join(parts)[1:]


3) special instructions and notes

After installing the upgraded packages, please make sure that
your mailing list config databases have not been retrieved by
attackers.

You can do so by checking for patterns like ".....///" in your
web servers access logs.

If this is the case:
- Reset all user passwords.

The last security update includes a new "change_member_pw"
script which can do that easily.

- Change the mailing list admin password.

- Optionally: Look for members which should not be in the list


4) package location and checksums

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 for installation from the maintenance web.

6) 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 recommend against subscribing to security lists that cause the
e-mail 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
file name of the rpm package that you have downloaded. Of course,
package authenticity verification can only target an uninstalled 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 .
