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 β€œmodify policy” privilege to execute arbitrary code via unspecified vectors that trigger a write to an uninitialized pointer.
