tcpdump, Ethereal, and other sniffer packages allow remote attackers to cause a denial of service via malformed DNS packets in which a jump offset refers to itself, which causes tcpdump to enter an infinite loop while decompressing the packet.

Security readout for executives and security teams

CVE-2000-0333 is a denial-of-service flaw in tcpdump, Ethereal, and similar packet sniffers. A malformed DNS packet can make the sniffer loop indefinitely while decoding packet compression, potentially disrupting traffic analysis or monitoring. Exposure is most likely on legacy monitoring hosts, forensic workstations, or network sensors running vulnerable tcpdump, Ethereal, or related sniffer packages against untrusted DNS traffic. Treat as a legacy monitoring reliability risk. Prioritize environments where packet sniffers support detection, incident response, or regulated logging, because failure could reduce visibility. Mitigation focus: Inventory packet-sniffing tools on monitoring and forensic systems.; Check current vendor or distribution guidance for CVE-2000-0333.; Upgrade, replace, or retire unsupported tcpdump and Ethereal installations..
