* [SECURITY] CVE-2013-4420.patch: Strip out leading slashes and any
pathname prefix containing ".." components (Closes: #731860). This is
done in th_get_pathname() (as well as to symlink targets when
extracting symlinks), not merely when extracting files, which means
applications calling that function will not see the stored
filename. There is no way to disable this behaviour, but it can be
expected that one will be provided when the issue is solved upstream.
* th_get_size-unsigned-int.patch: Make the th_get_size() macro cast the
result from oct_to_int() to unsigned int. This is the right fix for
bug #725938 on 64-bit systems, where a specially crafted tar file
would not cause an integer overflow, but a memory allocation of almost
16 exbibytes, which would certainly fail outright without harm.
