Vulnerability Name:

CVE-2000-0333 (CCN-4859)

Assigned:1999-05-31
Published:1999-05-31
Updated:2008-09-10
Summary: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.
