From 9907069f442c56c90b67accb2d8fbd046dfce6db Mon Sep 17 00:00:00 2001 From: Lukas Fleischer Date: Wed, 27 Feb 2013 11:00:26 +0100 Subject: Validate date/time when scanning items Bail out when reading dates such as "02/30/2013" from the appointments file. These *could* be converted into valid dates but since we never write invalid dates to that file, these indicate a user error. Fixes following test cases: * appointment-009.sh * appointment-012.sh * appointment-016.sh * appointment-019.sh * event-003.sh Signed-off-by: Lukas Fleischer --- src/recur.c | 19 +++++++++++++++++++ 1 file changed, 19 insertions(+) (limited to 'src/recur.c') diff --git a/src/recur.c b/src/recur.c index 6a3a902..8a2f79f 100644 --- a/src/recur.c +++ b/src/recur.c @@ -325,6 +325,14 @@ struct recur_apoint *recur_apoint_scan(FILE * f, struct tm start, struct tm end, char buf[BUFSIZ], *nl; time_t tstart, tend, tuntil; + EXIT_IF(!check_date(start.tm_year, start.tm_mon, start.tm_mday) || + !check_date(end.tm_year, end.tm_mon, end.tm_mday) || + !check_time(start.tm_hour, start.tm_min) || + !check_time(end.tm_hour, end.tm_min) || + (until.tm_year != 0 && !check_date(until.tm_year, until.tm_mon, + until.tm_mday)), + _("date error in appointment")); + /* Read the appointment description */ if (!fgets(buf, sizeof buf, f)) return NULL; @@ -368,6 +376,12 @@ struct recur_event *recur_event_scan(FILE * f, struct tm start, int id, char buf[BUFSIZ], *nl; time_t tstart, tuntil; + EXIT_IF(!check_date(start.tm_year, start.tm_mon, start.tm_mday) || + !check_time(start.tm_hour, start.tm_min) || + (until.tm_year != 0 && !check_date(until.tm_year, until.tm_mon, + until.tm_mday)), + _("date error in event")); + /* Read the event description */ if (!fgets(buf, sizeof buf, f)) return NULL; @@ -750,6 +764,11 @@ void recur_exc_scan(llist_t * lexc, FILE * data_file) &day.tm_mon, &day.tm_mday, &day.tm_year) != 3) { EXIT(_("syntax error in item date")); } + + EXIT_IF(!check_date(day.tm_year, day.tm_mon, day.tm_mday) || + !check_time(day.tm_hour, day.tm_min), + _("date error in item exception")); + day.tm_hour = 0; day.tm_min = day.tm_sec = 0; day.tm_isdst = -1; -- cgit v1.2.3-54-g00ecf
