Patch from Sergey Poznyakoff <gray@mirddin.farlep.net> for cpio
based on patch:
2007-08-15 Dmitry V. Levin <ldv@owl.openwall.com>
Do not use alloca to avoid stack overflow with untrusted input.
* lib/paxnames.c (hash_string_insert_direct): New function.
(hash_string_insert): Use it.
(hash_string_insert_data): New function.
(safer_name_suffix): Use it instead of hash_string_insert()
and alloca().

%description
This is GNU cpio, a program to manage archives of files. This package
also includes 'mt', a tape drive control program. Cpio copies files
into or out of a cpio or tar archive. An archive is a file that
contains other files plus information about them, such as their
pathname, owner, time stamps, and access permissions. The archive can
be another file on the disk, a magnetic tape, or a pipe.
This package normally includes the program 'rmt', which provides remote
tape drive control. Because there is a compatible 'rmt' in the 'dump'
package, 'rmt' is not included in this package. If you are planning to
use the remote tape features provided by cpio, install the 'dump'
package as well.
