epan/dissectors/packet-catapult-dct2000.c in the Catapult DCT2000 dissector in Wireshark 2.x before 2.0.6 does not restrict the number of channels, which allows remote attackers to cause a denial of service (buffer over-read and application crash) via a crafted packet.

Security readout for executives and security teams

This flaw can make vulnerable Wireshark 2.x versions crash when they process a specially crafted packet for the Catapult DCT2000 dissector. The documented impact is denial of service to the analysis application, not data theft or host takeover. Organizations should prioritize analyst workstations or systems that inspect untrusted traffic or capture files. Exposure is most likely where Wireshark 2.x before 2.0.6 is used to inspect untrusted packet captures or live traffic that can invoke the Catapult DCT2000 dissector. The source bundle does not identify server-side products beyond Wireshark or broader embedded exposure. Address during normal vulnerability remediation, faster for SOC, incident-response, or network-analysis teams handling untrusted captures. Business risk is disruption to analysis tooling rather than direct compromise, based on the provided sources. Mitigation focus: Upgrade Wireshark 2.x installations to 2.0.6 or later.; Apply Debian DSA-3671 packages where Debian-distributed Wireshark is used.; Avoid opening untrusted captures with vulnerable Wireshark versions..
