affected by the following vulnerabilities :
- 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. (CVE-2023-36054)
