Cistron RADIUS daemon (radiusd-cistron) 1.6.6 and earlier allows remote attackers to cause a denial of service and possibly execute arbitrary code via a large value in an NAS-Port attribute, which is interpreted as a negative number and causes a buffer overflow.

Security readout for executives and security teams

This is an old vulnerability in Cistron RADIUS daemon 1.6.6 and earlier. A remote attacker could send an oversized NAS-Port attribute that may crash the service and could possibly lead to arbitrary code execution. The main business risk is disruption or compromise of legacy authentication infrastructure. Exposure is likely limited to organizations still running Cistron radiusd, especially legacy Linux distributions or appliances using radiusd-cistron 1.6.6 or earlier. The bundle’s affected-product metadata is incomplete, so inventory confirmation is required. Prioritize remediation if Cistron RADIUS is still present, especially on authentication infrastructure. This is a legacy issue, but exposed vulnerable instances could affect availability and potentially host integrity. Mitigation focus: Identify all systems running Cistron radiusd or radiusd-cistron.; Check the listed vendor advisories for applicable fixed packages.; Upgrade or replace affected radiusd-cistron deployments per vendor guidance..
