SMB_MALLOC without NULL check

[Andreas Moroder]

Hello,

in samba 3 ( I started with git yesterday so I don't know what branch
this is ) I found this SMB_MALLOCs where the result is not checked
against NULL.

lib/util_str.c
function string_append  SMB_MALLOC  without NULL check


lib/util_unistr.c
load_case_tables  line 126
low_case_table allocated and not checked for NULL


libads/sasl.c line 989
function ads_sasl_gssapi_do_bind

        output_token.value = SMB_MALLOC(output_token.length);
        p = (uint8 *)output_token.value;


libnet/libnet_samsync_ldif.c
function  populate_ldap_for_ldif   in line 85

There are also 3 SMB_MALLOC without check in libsmb/cliconnect.c at line
2136 but I am not sure if a check is necessary.

Bye
Andreas
