From 3e09eb5c83e56bc0184bd9d9c44f76047464f77c Mon Sep 17 00:00:00 2001 From: Andreas Henriksson <andreas@fatal.se> Date: Fri, 13 Jun 2014 18:48:19 +0200 Subject: [PATCH] core: fix invalid free() in killall() static int killall(....) in ./src/core/killall.c tries to get "s" initialized by calling get_process_comm(...) which calls read_one_line_file(...) which if it fails will mean it is left uninitialized. It is then used in argument to strna(s) call where it is dereferenced(!), in addition to nothing else initializing it before the scope it is in finishes. --- src/core/killall.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git src/core/killall.c src/core/killall.c index 57ed41c..eab48f7 100644 --- src/core/killall.c +++ src/core/killall.c @@ -168,7 +168,7 @@ static int killall(int sig, Set *pids, bool send_sighup) { continue; if (sig == SIGKILL) { - _cleanup_free_ char *s; + _cleanup_free_ char *s = NULL; get_process_comm(pid, &s); log_notice("Sending SIGKILL to PID "PID_FMT" (%s).", pid, strna(s)); -- 1.7.9.2
