Of course, patching this is really trivial (I switched to asprintf() cause you never know how long a URL is, though I suppose you could go by the standards). And a patch is attached. >How-To-Repeat: ftp http://srcsys.org/work/penis-slapped-by-jkh.txt and then fetch http://srcsys.org/work/penis-slapped-by-jkh.txt >Fix: Aphex% cat host.patch --- /usr/src/usr.bin/ftp/fetch.c Wed Jan 31 08:24:39 2001 +++ fetch.c Fri Aug 24 19:49:29 2001 @@ -104,7 +104,7 @@ char *port; volatile int s; size_t len; - char c, *cp, *ep, *portnum, *path, buf[4096]; + char c, *cp, *ep, *http_buffer, *portnum, *path, buf[4096]; const char *savefile; char *line, *proxy, *host; volatile sig_t oldintr; @@ -280,12 +280,19 @@ printf("Requesting %s\n", origline); else printf("Requesting %s (via %s)\n", origline, proxyenv); - len = snprintf(buf, sizeof(buf), "GET %s%s HTTP/1.0\r\n\r\n", - proxy ?
