(HP Issues Fix Notice for HP Secure OS for Linux) OpenLDAP Stand-alone LDAP Server (slapd) Bug Lets Valid Remote Users Delete Attributes Without Authorization
SecurityTracker Alert ID:  1003370
SecurityTracker URL:  http://securitytracker.com/id/1003370
CVE Reference:   GENERIC-MAP-NOMATCH   (Links to External Site)
Date:  Jan 26 2002
Impact:   Modification of user information
Fix Available:  Yes  Vendor Confirmed:  Yes  
Version(s): 2.0.20; possibly prior versions
Description:   A vulnerability was reported in OpenLDAP's standalone LDAP server. A remote user can delete attributes without authorization.

It is reported that the stand-alone LDAP server (slapd) version 2.0.x allows entities with access to the LDAP service to make an unauthorized replacement of the values of arbitrary attributes with an empty set of values, deleting the attribute completely.

A demonstration exploit transcript is provided in the Source Message.

Impact:   A remote user with access to the LDAP server can delete arbitrary attributes without authorization.
Solution:   The vendor has released a fix notice for HP Secure OS for Linux and recommends that customers download the RPMs listed in the following Red Hat Security Advisory:

2002-01-22 openldap-clients (RHSA-2002-014) Updated OpenLDAP packages available.

http://www.redhat.com/support/errata/RHSA-2002-014.html

To install the security bulletin RPMs, use the following sequence of commands:

1. If you use the tripwire product, we recommend that you run a
a consistency check and fix any violations before installing
the security bulletin RPM.

tripwire --check --interactive

2. Install the bulletin RPM from the root account.

rpm -F <bulletin RPM name>

3. Update the tripwire database

tripwire --check --interactive



NOTE:
The rpm -q <package name> command can be used to determine if the
product is installed. Hewlett-Packard Company recommends applying the
Security Bulletin fixes to installed packages only. The -F option
to the RPM installer will only apply the fix if the package is
currently installed on the system. Dependent RPMs can be found by
using the "Find Latest RPMs" search facility at
http://www.redhat.com/apps/download. To find the latest dependent
RPM enter the RPM's name in the "By Keyword" box.
