Posted by LinuxSecurity.com Team   
RedHat Linux Updated OpenLDAP packages are now available for Red Hat Linux 7, 7.1, and7.2. These updates resolve a vulnerability which would allow users toremove non-mandatory attributes from any object in a directory.

---------------------------------------------------------------------
                   Red Hat, Inc. Red Hat Security Advisory

Synopsis:          Updated OpenLDAP packages available
Advisory ID:       RHSA-2002:014-07
Issue date:        2002-01-14
Updated on:        2002-01-22
Product:           Red Hat Linux
Keywords:          openldap acl
Cross references:  
Obsoletes:         RHSA-2001:098
---------------------------------------------------------------------

1. Topic:

Updated OpenLDAP packages are now available for Red Hat Linux 7, 7.1, and
7.2.  These updates resolve a vulnerability which would allow users to
remove non-mandatory attributes from any object in a directory.

2. Relevant releases/architectures:

Red Hat Linux 7.0 - alpha, i386

Red Hat Linux 7.1 - alpha, i386, ia64

Red Hat Linux 7.2 - i386, ia64

3. Problem description:

Versions of OpenLDAP from 2.0.0 through 2.0.19 do not check permissions
using access control lists when a user attempts to remove an attribute from
an object in the directory by replacing its values with an empty list. 
Because schema checking is still enforced, a user can only remove
attributes which the schema does not require the object to possess.

These packages update OpenLDAP to version 2.0.21 which is not vulnerable to
this problem.

4. Solution:

Before applying this update, make sure all previously released errata
relevant to your system have been applied.

To update all RPMs for your particular architecture, run:

rpm -Fvh [filenames]

where [filenames] is a list of the RPMs you wish to upgrade.  Only those
RPMs which are currently installed will be updated.  Those RPMs which are
not installed but included in the list will not be updated.  Note that you
can also use wildcards (*.rpm) if your current directory *only* contains the
desired RPMs.

Please note that this update is also available via Red Hat Network.  Many
people find this an easier way to apply updates.  To use Red Hat Network,
launch the Red Hat Update Agent with the following command:

up2date

This will start an interactive process that will result in the appropriate
RPMs being upgraded on your system.
