CVE-2007-2798: Stack-based buffer overflow in the rename_principal_2_svc function in kadmind for MIT Kerberos 1.5.3, 1.6.1...

Security readout for executives and security teams

This flaw affects the Kerberos administration daemon, a component used to manage identities. A user who can authenticate to the service could send a malformed principal rename request and potentially run code on the server. Because Kerberos is core authentication infrastructure, compromise could have broad operational impact. Exposure is most likely in legacy MIT Kerberos deployments or downstream operating-system packages that still include vulnerable kadmind code. References include Ubuntu, Red Hat, Apple, Gentoo, VMware, and other advisories, so vulnerability managers should verify vendor-specific package status rather than assume only upstream MIT builds are relevant. Treat as high priority where legacy Kerberos administration servers remain in use. The authentication requirement reduces opportunistic exposure, but successful compromise could undermine identity administration. If no kadmind service or vulnerable package exists, priority drops to documentation and evidence retention. Mitigation focus: Update MIT Kerberos or vendor Kerberos packages according to applicable vendor advisories.; Restrict kadmind network access to trusted administration hosts only.; Review Kerberos administrative principals and remove unnecessary privileges..
