The remote Gentoo host is missing one or more security-related
The remote host is affected by the vulnerability described in GLSA-200409-16
(Samba: Denial of Service vulnerabilities)
There is a defect in smbd's ASN.1 parsing. A bad packet received during the
authentication request could throw newly-spawned smbd processes into an
infinite loop (CAN-2004-0807). Another defect was found in nmbd's
processing of mailslot packets, where a bad NetBIOS request could crash the
nmbd process (CAN-2004-0808).
A remote attacker could send specially crafted packets to trigger both
defects. The ASN.1 parsing issue can be exploited to exhaust all available
memory on the Samba host, potentially denying all service to that server.
The nmbd issue can be exploited to crash the nmbd process, resulting in a
Denial of Service condition on the Samba server.
There is no known workaround at this time.
