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 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...
