epan/dissectors/packet-diameter.c in the DIAMETER dissector in Wireshark 1.4.x before 1.4.13 and 1.6.x before 1.6.8 does not properly construct certain array data structures, which allows remote attackers to cause a denial of service (application crash) via a crafted packet that triggers incorrect memory allocation.

Security readout for executives and security teams

This flaw can crash older Wireshark versions when they process a specially crafted DIAMETER packet. The business impact is disruption to packet analysis, monitoring, or troubleshooting workflows, not data theft or system takeover based on the provided sources. Exposure is most likely in legacy Wireshark installations or systems that automatically inspect untrusted network traffic or capture files. Modern supported Wireshark deployments should not be affected if updated beyond the fixed versions. Treat this as a legacy hygiene and monitoring resilience issue. Remediate where old Wireshark is still used, especially in security operations, but do not escalate as active exploitation without new evidence. Mitigation focus: Upgrade Wireshark 1.4.x to 1.4.13 or later.; Upgrade Wireshark 1.6.x to 1.6.8 or later.; Prioritize packet-analysis systems processing untrusted traffic or captures..
