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 ==========
