The Key Distribution Center (KDC) in Kerberos 5 (krb5) 1.2.7 and earlier allows remote, authenticated attackers to cause a denial of service (crash) on KDCs within the same realm using a certain protocol request that causes the KDC to corrupt its heap (aka "buffer underrun").

Security readout for executives and security teams

CVE-2003-0082 is a denial-of-service flaw in Kerberos 5 KDC servers. An authenticated user in the same Kerberos realm could send a malformed protocol request that crashes the KDC, disrupting authentication-dependent services. Exposure is most likely in legacy environments still running Kerberos 5 krb5 1.2.7 or earlier, including old Unix/Linux Kerberos packages referenced by vendor advisories. Modern maintained Kerberos deployments are unlikely to be affected, but inherited KDC infrastructure should be checked. Treat as a legacy authentication availability risk. It is not currently evidenced as actively exploited, but any affected production KDC could become a single point of business disruption. Mitigation focus: Identify any KDCs running krb5 1.2.7 or earlier.; Review MIT Kerberos and operating-system vendor advisories for fixed packages.; Upgrade or replace affected Kerberos packages using supported vendor guidance..
