From a496700b3a67ccb494385bfb22ebab0027af6e60 Mon Sep 17 00:00:00 2001 From: Andy Green Date: Thu, 15 Sep 2016 02:22:57 +0800 Subject: [PATCH] lws_snprintf Thanks to Fabrice Gilot for reporting the problem that led to uncovering this. Due to a misunderstanding of the return value of snprintf (it is not truncated according to the max size passed in) in several places relying on snprintf to truncate the length overflows are possible. This patch wraps snprintf with a new lws_snprintf() which does truncate its length to allow the buffer limiting scheme to work properly. All users should update with these fixes. --- doc/html/globals_func.html | 3 + doc/html/globals_l.html | 3 + doc/html/group__misc.html | 53 +++++++++++ doc/html/group__misc.js | 1 + doc/html/group__smtp.html | 18 ++-- doc/html/libwebsockets_8h.html | 2 + doc/html/libwebsockets_8h.js | 1 + doc/html/libwebsockets_8h_source.html | 69 +++++++------- doc/html/navtreedata.js | 6 +- doc/html/navtreeindex0.js | 12 +-- doc/html/navtreeindex1.js | 36 ++++---- doc/html/navtreeindex2.js | 50 +++++----- doc/html/navtreeindex3.js | 16 ++-- doc/html/navtreeindex4.js | 14 +-- lib/client-handshake.c | 26 +++--- lib/lejp-conf.c | 18 ++-- lib/libuv.c | 10 +- lib/libwebsockets.c | 92 +++++++++++-------- lib/libwebsockets.h | 16 +++- lib/lws-plat-esp8266.c | 2 +- lib/lws-plat-unix.c | 6 +- lib/private-libwebsockets.h | 2 +- lib/server.c | 12 +-- plugins/generic-sessions/handlers.c | 42 ++++----- .../protocol_generic_sessions.c | 20 ++-- .../protocol_lws_messageboard.c | 12 +-- plugins/generic-sessions/utils.c | 24 ++--- .../generic-table/protocol_table_dirlisting.c | 42 ++++----- plugins/protocol_dumb_increment.c | 2 +- plugins/protocol_lws_status.c | 4 +- plugins/protocol_post_demo.c | 6 +- test-server/test-fraggle.c | 2 +- test-server/test-ping.c | 2 +- test-server/test-server-http.c | 6 +- test-server/test-server-status.c | 4 +- 35 files changed, 367 insertions(+), 267 deletions(-) diff --git a/doc/html/globals_func.html b/doc/html/globals_func.html index 0dec7474..d3ca228d 100644 --- a/doc/html/globals_func.html +++ b/doc/html/globals_func.html @@ -354,6 +354,9 @@ $(document).ready(function(){initNavTree('globals_func.html','');});

    strdestination buffer

    formatformat string

    This lets you correctly truncate buffers by concatenating lengths, if you reach the limit the reported length doesn't exceed the limit.
