Synopsis
========

The OpenLDAP replication server slurpd contains a buffer
overflow that
could result in arbitrary code execution.

Background
==========

OpenLDAP is a suite of LDAP-related applications and
development tools.
It includes slapd (the standalone LDAP server), slurpd (the
standalone
LDAP replication server), various LDAP libraries, utilities
and example
clients.

Affected packages
=================

   
------------------------------------------------------------
-------
     Package           /  Vulnerable  /                    
Unaffected
   
------------------------------------------------------------
-------
  1  net-nsd/openldap      < 2.3.22                      
   >= 2.3.22

Description
===========

slurpd contains a buffer overflow when reading very long
hostnames from
the status file.

Impact
======

By injecting an overly long hostname in the status file, an
attacker
could possibly cause the execution of arbitrary code with
the
permissions of the user running slurpd.

Workaround
==========

There is no known workaround at this time.

Resolution
==========

All openLDAP users should upgrade to the latest version:

    # emerge --sync
    # emerge --ask --oneshot --verbose
">=net-nds/openldap-2.3.22"
