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.
</p>
</description>
<impact type="low">
<p>
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.
</p>
</impact>
<workaround>
<p>
There is no known workaround at this time.
</p>
</workaround>
<resolution>
<p>
All OpenLDAP users should upgrade to the latest version:
</p>
<code>
# emerge --sync
# emerge --ask --oneshot --verbose &quot;&gt;=net-nds/openldap-2.3.43&quot;</code>
</resolution>
