epan/dissectors/packet-h225.c in the H.225 dissector in Wireshark 2.x before 2.0.6 calls snprintf with one of its input buffers as the output buffer, which allows remote attackers to cause a denial of service (copy overlap and application crash) via a crafted packet.

Security readout for executives and security teams

A malicious or malformed network packet can crash vulnerable Wireshark 2.x versions before 2.0.6 when they parse H.225 traffic. This is mainly an availability risk to analysts, monitoring systems, and automated packet-processing workflows, not a documented system compromise issue. Exposure is most likely where vulnerable Wireshark or tshark versions inspect live traffic, packet captures, or automated analysis feeds containing H.225/H.323 protocol data. Treat this as a focused operational risk. It can disrupt packet analysis and monitoring, especially in SOC or forensic workflows, but the cited evidence supports denial of service only. Mitigation focus: Upgrade Wireshark 2.x deployments to 2.0.6 or later.; Apply Debian DSA-3671 packages where Debian-managed Wireshark is used.; Prioritize systems that process untrusted packet captures or live network traffic..
