The RADIUS decoder in tcpdump 3.6.2 and earlier allows remote attackers to cause a denial of service (crash) via an invalid RADIUS packet with a header length field of 0, which causes tcpdump to generate data within an infinite loop.

Security readout for executives and security teams

This issue can make tcpdump crash when it processes a malformed RADIUS packet. It affects tcpdump 3.6.2 and earlier. Business impact is mainly loss of packet-capture visibility or troubleshooting capability, not confirmed system compromise. Exposure is most likely on legacy Linux or Unix systems, network monitoring hosts, security appliances, or incident-response toolkits still running tcpdump 3.6.2 or earlier and inspecting RADIUS traffic. Treat this as a targeted legacy-risk cleanup. Prioritize systems used for monitoring or incident response because a crash could reduce visibility during network events. Mitigation focus: Inventory tcpdump installations and identify versions 3.6.2 or earlier.; Review Debian, Red Hat, and Mandrake advisories for fixed packages.; Update tcpdump using the relevant vendor or distribution package channel..
