From 5abe86f88de3c61e369483a55afe771cce646135 Mon Sep 17 00:00:00 2001

Subject: [PATCH 3/4] CVE-2016-2037 - 1 byte out-of-bounds write
Ensure that cpio_safer_name_suffix always works with dynamically
allocated buffer, and that it has size of at least 32 bytes.
Then, any call to cpio_safer_name_suffix is safe (it requires at
least 2 bytes in the buffer).
Also ensure that c_namesize is always correctly initialized (by
cpio_set_c_name) to avoid undefined behavior when reading
file_hdr.c_namesize (previously happened for tar archives).
References:
http://www.mail-archive.com/bug-cpio@gnu.org/msg00545.html
* src/copyin.c (query_rename): Drop the hack, as we now work with
dynamically allocated buffer. Use cpio_set_c_name.
(create_defered_links_to_skipped): Use cpio_set_c_name rather than
manual assignment.
(read_name_from_file): New function to avoid C&P.
(read_in_old_ascii, read_in_new_ascii, read_in_binary): Use
read_name_from_file.
(process_copy_in): Initialize file_hdr.c_namesize.
* src/copyout.c (process_copy_out): Use cpio_set_c_name.
* src/cpiohdr.h (cpio_set_c_name): New prototype.
* src/tar.c (read_in_tar_header): Use cpio_set_c_name.
* src/util.c (cpio_set_c_name): New function to set
file_hdr->c_name and c_namesize from arbitrary string.
(cpio_safer_name_suffix): Some docs fixes.
* tests/inout.at: Also test copy-in, and try various formats.
