NULL pointer write on "bulkget system icmp"
snmp_agent.c:handle_one_var() doesn't check NULL value of return pointer
after calling snmp_add_null_var(). On my setup, writes to NULL pointer
structure from a "bulkget system icmp" request.
Not sure why snmp_add_null_var() returned NULL (many cases do) or what
proper fix is.
It's here:
http://exr.lunn.ch/http/source/packages/net/snmp/agent/current/src/snmp_agent.c#L453
var_ptr2 = snmp_add_null_var(asp->pdu, var_ptr->name, MAX_OID_LEN);
for ( i=var_ptr->name_length ; i<MAX_OID_LEN ; i++)
!!! var_ptr2->name[i] = 0;
!!! var_ptr2->name_length = var_ptr->name_length;
allDone = FALSE;
