CVE-2023-36054
Fixed in a distro release EPSS 3%
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.
Products: mit kerberos_5, debian_linux, netapp active_iq_unified_manager, netapp clustered_data_ontap, netapp hci, netapp management_services_for_element_software, netapp ontap_tools
