Gentoo Linux Security Advisory

Title: TCPDump: Decoding routines Denial of Service vulnerability (GLSA 200505-06)
Severity: normal
Exploitable: remote
Date: May 09, 2005
Updated: June 12, 2005
Bug(s): #90541, #95349
ID: 200505-06

Synopsis


A flaw in the decoding of network packets renders TCPDump vulnerable to a
remote Denial of Service attack.


Background


TCPDump is a tool for network monitoring and data acquisition.


Affected Packages

Package: net-analyzer/tcpdump
Vulnerable: < 3.8.3-r3
Unaffected: >= 3.8.3-r3
Architectures: All supported architectures


Description


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.


Resolution


All TCPDump users should upgrade to the latest available version:
Code:
# emerge --sync
    # emerge --ask --oneshot --verbose ">=net-analyzer/tcpdump-3.8.3-r3"
