I tried to compile it myself but an error appear, actually there was more errors but I added -std=c99 to flags. I'm not good at programming C 😞

libcs2d.c: In function 'cs2d_request_ips': libcs2d.c:27:5: warning: implicit declaration of function 'bcopy' [-Wimplicit-function-declaration] bcopy(usgn->h_addr, &(server.sin_addr.s_addr), 4); ^ libcs2d.c:27:15: error: 'struct hostent' has no member named 'h_addr' bcopy(usgn->h_addr, &(server.sin_addr.s_addr), 4); ^ Makefile:2: recipe for target 'compile' failed make: *** [compile] Error 1

        int map_len = response[loc];
        loc++;
        strncpy(sv->mapName, &response[loc], map_len);
        sv->mapName[map_len] = '\0';

The strncpy of the sv->name is also vulnerable. You should be sizing against your destination, not with untrusted data from the wire.
