The kadm5_modify_policy_internal function in lib/kadm5/srv/svr_policy.c in the Kerberos administration daemon (kadmind) in MIT Kerberos 5 (krb5) 1.5 through 1.6.2 does not properly check return values when the policy does not exist, which might allow remote authenticated users with the "modify policy" privilege to execute arbitrary code via unspecified vectors that trigger a write to an uninitialized pointer.

Security readout for executives and security teams

CVE-2007-4000 affects the MIT Kerberos administration daemon. A specially privileged authenticated user may be able to crash or take control of the admin service because an error path can write through an uninitialized pointer. Exposure is most relevant to Kerberos administrative servers running MIT krb5 1.5 through 1.6.2 with kadmind enabled and accounts granted the "modify policy" privilege. Treat as high priority for legacy Kerberos environments because compromise of an admin daemon can affect authentication governance. Urgency is lower where krb5 is newer or modify-policy privileges are tightly controlled. Mitigation focus: Inventory Kerberos admin servers running MIT krb5 1.5 through 1.6.2.; Review MIT and distribution advisories for fixed krb5 packages.; Apply the appropriate vendor krb5 update where available..
