Package        : zope-ldapuserfolder
Vulnerability  : missing input validation
Problem type   : remote
Debian-specific: no
CVE Id         : CVE-2010-2944
Debian Bug     : 593466

Jeremy James discovered that in zope-ldapuserfolder, a Zope extension
used to authenticate against an LDAP server, the authentication code
does not verify the password provided for the emergency user. Malicious
users that manage to get the emergency user login can use this flaw to
gain administrative access to the Zope instance, by providing an
arbitrary password.

For the stable distribution (lenny), this problem has been fixed in
version 2.9-1+lenny1.

The package no longer exists in the upcoming stable distribution
(squeeze) or the unstable distribution.

We recommend that you upgrade your zope-ldapuserfolder 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.
