New submission from Christian Heimes:
Under rare circumstances listdir() could leak a FD:
- HAVE_FDOPENDIR is defined
- dup(fd) succeeds
- fdopendir() fails and sets dirp to NULL
- if (dirp == NULL) goto exit
- the dupped fd isn't closed because exit just handles dirp != NULL.
Proposed fix:
if (dirp != NULL) {
...
} else if (fd != -1) {
close(fd);
}
