Hi,
The following vulnerability was published for krb5.
CVE-2023-36054[0]:
| 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.
If you fix the vulnerability please also make sure to include the
CVE (Common Vulnerabilities & Exposures) id in your changelog entry.
