A flaw in OpenLDAP allows remote unauthenticated attackers to cause a Denial of Service.
OpenLDAP Software is an open source implementation of the Lightweight Directory Access Protocol.
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.
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.
There is no known workaround at this time.
All OpenLDAP users should upgrade to the latest version:
