    Yup.. definately your standard buffer overflow..
    
    On line 306 of snmpd.c, they have:
    char            logfile[SNMP_MAXBUF_SMALL];
    
    They define SNMP_MAXBUF_SMALL in tools.h as a 512k buffer.
    
    And last but not least, on line 321 of snmpd.c:
    strcpy(logfile, LOGFILE);
