CVE-2023-36054
A remote authenticated user can trigger a kadmind crash.
MEDIUM 6.5EPSS 2.81%
Does this matter?
Lower severity and a low EPSS score (2.81%). Track it; it rarely justifies an emergency change on its own.
Description
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.
