    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.
