Description
lib/kadm5/kadm_rpc_xdr.c in MIT Kerberos 5 (aka krb5) before 1.20.2 and 1.21.x before 1.21.1 frees an uninitialized pointer. A remote authenticated user can trigger a kadmind crash. This occurs because _xdr_kadm5_principal_ent_rec does not validate the relationship between n_key_data and the key_data array count.
Affected configurations
• mit kerberos 5 (< 1.20.2)
• mit kerberos 5 1.21
• debian debian linux 10.0
• netapp active iq unified manager
• netapp clustered data ontap 9.0
• netapp hci
• netapp management services for element software
• netapp ontap tools
