Synopsis
========

A flaw in OpenLDAP allows remote unauthenticated attackers to cause a
Denial of Service.

Background
==========

OpenLDAP Software is an open source implementation of the Lightweight
Directory Access Protocol.

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

-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 net-nds/openldap < 2.3.43 >= 2.3.43

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

Cameron Hotchkies discovered an error within the parsing of ASN.1 BER
encoded packets in the "ber_get_next()" function in
libraries/liblber/io.c.

Impact
======

A remote unauthenticated attacker can send a specially crafted ASN.1
BER encoded packet which will trigger the error and cause an
"assert()", terminating the "slapd" daemon.

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-2.3.43"

References
==========
