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"
