Package        : nss-ldapd
Vulnerability  : insecure config file creation
Problem-Type   : local
Debian-specific: yes
CVE ID         : CVE-2009-1073
Debian Bug     : 520476

Leigh James that discovered that nss-ldapd, an NSS module for using
LDAP as a naming service, by default creates the configuration file
/etc/nss-ldapd.conf world-readable which could leak the configured
LDAP password if one is used for connecting to the LDAP server.

The old stable distribution (etch) doesn't contain nss-ldapd.

For the stable distribution (lenny) this problem has been fixed in
version 0.6.7.1.

For the unstable distribution (sid) this problem has been fixed in
version 0.6.8.

We recommend that you upgrade your nss-ldapd 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.
