[Full-disclosure] ICMP attacks against TCP: Conclusions

Folks, My posts to this list have tried to show how easy it is to perform ICMP attacks against TCP. The attacks are blind, so the attacker does not need to be a "man in the middle" to perform then. The typical number of packets required to perform any of these attacks is about 16000 in many cases...

Slackware 10.0 / 10.1 / 8.1 / 9.0 / 9.1 / current : tcpdump DoS (SSA:2005-195-10)

New tcpdump packages are available for Slackware 8.1, 9.0, 9.1, 10.0, 10.1, and -current to fix a security issue. A specially crafted BGP packet can cause tcpdump to go into an infinite loop, creating a denial of service where network monitoring is disabled. %NASLMINLEVEL 70300 C Tenable Network...

ICMP vulnerabilities

Much more information on the ICMP vulnerabilities that allow you to blindly tear down TCP sessions. http://kerneltrap.org/node/5382 Please note these are not man-in-the-middle attacks. You can do them blind. Totally blind. You do not need to know any information. There are three attacks outlined...

Fedora Core 4 : tcpdump-3.8.2-13.FC4 (2005-407)

USN-141-1: tcpdump vulnerability

It was discovered that certain invalid BGP packets triggered an infinite loop in tcpdump, which caused tcpdump to stop working. This could be abused by a remote attacker to bypass tcpdump analysis of network traffic...

Another tcpdump BGP infinite loop vulnerability (CAN-2005-1267)

Hello While working on the FreeBSD Security Advisory for the recent tcpdump issues CAN-2005-1278, CAN-2005-1279, and CAN-2005-1280 I noticed another similar infinite loop DoS vulnerability in the BGP handling code. It affects at least tcpdump 3.8.3 and tcpdump 3.9 snapshots from before May 5. The...

CVE-2005-1267

The bgpupdateprint function in tcpdump 3.x does not properly handle a -1 return value from the decodeprefix4 function, which allows remote attackers to cause a denial of service infinite loop via a crafted BGP packet...

CVE-2005-1267

The CVE-2005-1267 issue affects the BGP dissector in tcpdump (v3.x). The vuln arises when bgp_update_print fails to handle a -1 return from decode_prefix4, enabling a remote attacker to trigger a denial-of-service via an infinite loop by sending a crafted BGP packet. The impact is a DoS on affect...
