Medium Nessus Plugin ID 33855


The remote Gentoo host is missing one or more security-related patches.


The remote host is affected by the vulnerability described in GLSA-200808-09 (OpenLDAP: Denial of Service vulnerability)

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.


All OpenLDAP users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose '>=net-nds/openldap-2.3.43'
