commit 37d16c3cc78151daf2cbebd643ea4d64b504989e Author: Sebastian Hahn <sebast...@torproject.org> Date: Mon Feb 9 04:48:16 2015 +0100
Reserve enough space for rend_service_port_config_t In #14803, Damian noticed that his Tor sometimes segfaults. Roger noted that his valgrind gave an invalid write of size one here. Whenever we use FLEXIBLE_ARRAY_MEMBER, we have to make sure to actually malloc a thing that's large enough. Fixes bug #14803, not in any released version of Tor. --- src/or/rendservice.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/src/or/rendservice.c b/src/or/rendservice.c index 6ae569c..6c934c8 100644 --- a/src/or/rendservice.c +++ b/src/or/rendservice.c @@ -314,7 +314,7 @@ static rend_service_port_config_t * rend_service_port_config_new(const char *socket_path) { if (!socket_path) - return tor_malloc_zero(sizeof(rend_service_port_config_t)); + return tor_malloc_zero(sizeof(rend_service_port_config_t) + 1); const size_t pathlen = strlen(socket_path) + 1; rend_service_port_config_t *conf = _______________________________________________ tor-commits mailing list tor-commits@lists.torproject.org https://lists.torproject.org/cgi-bin/mailman/listinfo/tor-commits
