The phar_make_dirstream function in ext/phar/dirstream.c in PHP before
5.6.18 and 7.x before 7.0.3 mishandles zero-size ././@LongLink files, which
allows remote attackers to cause a denial of service (uninitialized pointer
dereference) or possibly have unspecified other impact via a crafted TAR
archive.
