CVE-2005-0006: The COPS dissector in Ethereal 0.10.6 through 0.10.8 allows remote attackers to cause a denial of service (...

Security readout for executives and security teams

This is an old denial-of-service flaw in Ethereal versions 0.10.6 through 0.10.8. A specially formed COPS packet or capture could make the COPS dissector loop indefinitely, tying up the analyzer. It affects availability of the tool, not data confidentiality or system takeover based on the supplied sources. Exposure is most likely in legacy systems, old Linux distributions, forensic workstations, lab images, or appliances that still include Ethereal 0.10.6 through 0.10.8 and inspect untrusted network traffic or packet captures. Handle through legacy exposure management. It is not presented as actively exploited, but affected tools can be disabled by crafted traffic. Prioritize if old packet-analysis systems touch hostile networks, incident-response captures, or regulated operational environments. Mitigation focus: Identify and remove Ethereal 0.10.6 through 0.10.8 where present.; Apply relevant vendor updates from Ethereal, Red Hat, Gentoo, Mandrake, or Fedora guidance.; Avoid processing untrusted COPS traffic or captures with affected Ethereal versions..
