Debian Security Advisory DSA 830-1 - Drew Parsons noticed that the post-installation script of ntlmaps, an NTLM authorization proxy server, changes the permissions of the configuration file to be world-readable. It contains the user name and password of the Windows NT system that ntlmaps connects to and, hence, leaks them to local users.

Package        : ntlmaps
Vulnerability  : wrong permissons
Problem type   : local
Debian-specific: yes
CVE ID         : CAN-2005-2962

Drew Parsons noticed that the post-installation script of ntlmaps, an
NTLM authorisation proxy server, changes the permissions of the
configuration file to be world-readable.  It contains the user name
and password of the Windows NT system that ntlmaps connects to and,
hence, leaks them to lokal users.

The old stable distribution (woody) does not contain an ntlmaps package.

For the stable distribution (sarge) this problem has been fixed in
version 0.9.9-2sarge1.

For the unstable distribution (sid) this problem has been fixed in
version 0.9.9-4.

We recommend that you upgrade your ntlmaps package.


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.
