CVE-2000-0333: Ethereal Group Ethereal

Medium severity, CVSS 5.0. EPSS: 7.6% chance of exploitation in the next 30 days.

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.

Affected products

• Ethereal Group Ethereal: version 0.8.4 only; version 0.8.5 only; version 0.8.6 only
• Lbl Tcpdump: version 3.4 only; version 3.5a only
