medium Tenable Cloud Security Plugin ID 405089

Description

There are packages installed that are affected by multiple vulnerabilities referenced in the following CVEs:

- The xdr_nullstring function in lib/kadm5/kadm_rpc_xdr.c in kadmind in MIT Kerberos 5 (aka krb5) before
1.13.4 and 1.14.x before 1.14.1 does not verify whether '\0' characters exist as expected, which allows
remote authenticated users to obtain sensitive information or cause a denial of service (out-of-bounds
read) via a crafted string. (CVE-2015-8629)

- The (1) kadm5_create_principal_3 and (2) kadm5_modify_principal functions in lib/kadm5/srv/svr_principal.c
in kadmind in MIT Kerberos 5 (aka krb5) 1.12.x and 1.13.x before 1.13.4 and 1.14.x before 1.14.1 allow
remote authenticated users to cause a denial of service (NULL pointer dereference and daemon crash) by
specifying KADM5_POLICY with a NULL policy name. (CVE-2015-8630)

- Multiple memory leaks in kadmin/server/server_stubs.c in kadmind in MIT Kerberos 5 (aka krb5) before
1.13.4 and 1.14.x before 1.14.1 allow remote authenticated users to cause a denial of service (memory
consumption) via a request specifying a NULL principal name. (CVE-2015-8631)
