  "details" : [ "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.", "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)." ],
