GLSA-200505-06 : TCPDump: Decoding routines Denial of Service vulnerability

This script is Copyright (C) 2005-2014 Tenable Network Security, Inc.


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-200505-06
(TCPDump: Decoding routines Denial of Service vulnerability)

TCPDump improperly handles and decodes ISIS (CAN-2005-1278), BGP
(CAN-2005-1267, CAN-2005-1279), LDP (CAN-2005-1279) and RSVP
(CAN-2005-1280) packets. TCPDump might loop endlessly after receiving
malformed packets.

Impact :

A malicious remote attacker can exploit the decoding issues for a
Denial of Service attack by sending specially crafted packets, possibly
causing TCPDump to loop endlessly.

Workaround :

There is no known workaround at this time.

# emerge --sync
# emerge --ask --oneshot --verbose '>=net-analyzer/tcpdump-3.8.3-r3'
