libarchive: security bump to version 3.3.2

CVE-2016-8687: Stack-based buffer overflow in the safe_fprintf function
in tar/util.c in libarchive 3.2.1 allows remote attackers to cause a
denial of service via a crafted non-printable multibyte character in a
filename.

CVE-2016-8688: The mtree bidder in libarchive 3.2.1 does not keep track
of line sizes when extending the read-ahead, which allows remote
attackers to cause a denial of service (crash) via a crafted file, which
triggers an invalid read in the (1) detect_form or (2) bid_entry
function in libarchive/archive_read_support_format_mtree.c.

CVE-2016-8689: The read_Header function in
archive_read_support_format_7zip.c in libarchive 3.2.1 allows remote
attackers to cause a denial of service (out-of-bounds read) via multiple
EmptyStream attributes in a header in a 7zip archive.

CVE-2016-10209: The archive_wstring_append_from_mbs function in
archive_string.c in libarchive 3.2.2 allows remote attackers to cause a
denial of service (NULL pointer dereference and application crash) via a
crafted archive file.

CVE-2016-10349: The archive_le32dec function in archive_endian.h in
libarchive 3.2.2 allows remote attackers to cause a denial of service
(heap-based buffer over-read and application crash) via a crafted file.

CVE-2016-10350: The archive_read_format_cab_read_header function in
archive_read_support_format_cab.c in libarchive 3.2.2 allows remote
attackers to cause a denial of service (heap-based buffer over-read and
application crash) via a crafted file.

CVE-2017-5601: An error in the lha_read_file_header_1() function
(archive_read_support_format_lha.c) in libarchive 3.2.2 allows remote
attackers to trigger an out-of-bounds read memory access and
subsequently cause a crash via a specially crafted archive.

Add upstream patch fixing the following issue:

CVE-2017-14166: libarchive 3.3.2 allows remote attackers to cause a
denial of service (xml_data heap-based buffer over-read and application
crash) via a crafted xar archive, related to the mishandling of empty
strings in the atol8 function in archive_read_support_format_xar.c.
