The phar_parse_tarfile function in ext/phar/tar.c in PHP before 5.4.41,
5.5.x before 5.5.25, and 5.6.x before 5.6.9 does not verify that the first
character of a filename is different from the \0 character, which allows
remote attackers to cause a denial of service (integer underflow and memory
corruption) via a crafted entry in a tar archive.
