From f98c250300bd7303bb7b706384ec153101a3eab0 Mon Sep 17 00:00:00 2001 From: Martin Blix Grydeland Date: Thu, 15 Aug 2019 10:44:00 +0200 Subject: [PATCH] Allow a NULL value in http_Proto The proto field is optional in HTTP, so it may not be set. Set the proto to 0 also for a NULL value instead of segfaulting if it were NULL. --- bin/varnishd/cache/cache_http.c | 3 ++- 1 file changed, 2 insertions(+), 1 deletion(-) diff --git a/bin/varnishd/cache/cache_http.c b/bin/varnishd/cache/cache_http.c index 23eaa0b183..070ead2e6b 100644 --- a/bin/varnishd/cache/cache_http.c +++ b/bin/varnishd/cache/cache_http.c @@ -212,7 +212,8 @@ http_Proto(struct http *to) fm = to->hd[HTTP_HDR_PROTO].b; - if ((fm[0] == 'H' || fm[0] == 'h') && + if (fm != NULL && + (fm[0] == 'H' || fm[0] == 'h') && (fm[1] == 'T' || fm[1] == 't') && (fm[2] == 'T' || fm[2] == 't') && (fm[3] == 'P' || fm[3] == 'p') &&
