CVE-2023-36054

A vulnerability was found in the _xdr_kadm5_principal_ent_rec() function in lib/kadm5/kadm_rpc_xdr.c in MIT Kerberos 5 (krb5). This issue occurs due to lack of validation in the relationship between n_key_data and the key_data array count, leading to the freeing of uninitialized pointers. This may allow a remote authenticated attacker to send a specially crafted request that causes the kadmind process to crash, resulting in a denial of service (DoS).
