Package: libc6
Version: 2.2.5-14.3
Severity: normal
strftime() causes a segmentation fault if some of the values in the tm
argument are outside of its expected range. Here is a sample program:
#include <stdio.h>
#include <time.h>
int main() {
struct tm tmStruct;
char buf[256];
tmStruct.tm_year = 0;
tmStruct.tm_mon = 0;
tmStruct.tm_mday = 1;
tmStruct.tm_hour = 0;
tmStruct.tm_min = 0;
tmStruct.tm_sec = 0;
/* here is the problem: tm_wday is set to -1; I initially
* encountered this because I was setting tm_wday to -1 and then
* calling mktime, and not checking the return value from mktime
* before calling strftime */
tmStruct.tm_wday = -1;
tmStruct.tm_yday = 0;
tmStruct.tm_isdst = 0;
strftime(buf, sizeof(buf), "%c", &tmStruct);
return 0;
}
