		<Note Title="Synopsis" Type="General" Ordinal="1" xml:lang="en">krb5 security update</Note>
		<Note Title="Summary" Type="General" Ordinal="2" xml:lang="en">An update for krb5 is now available for openEuler-20.03-LTS-SP1.</Note>
		<Note Title="Description" Type="General" Ordinal="3" xml:lang="en">Kerberos is a network authentication protocol. It is designed to provide strong authentication for client/server applications by using secret-key cryptography.

Security Fix(es):

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)</Note>
		<Note Title="Topic" Type="General" Ordinal="4" xml:lang="en">An update for krb5 is now available for openEuler-20.03-LTS-SP1.

openEuler Security has rated this update as having a security impact of medium. A Common Vunlnerability Scoring System(CVSS)base score,which gives a detailed severity rating, is available for each vulnerability from the CVElink(s) in the References section.</Note>
