Synopsis :

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

Description :

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.
