CVE-2013-0211

Integer signedness error in the archive_write_zip_data function in
archive_write_set_format_zip.c in libarchive 3.1.2 and earlier, when
running on 64-bit machines, allows context-dependent attackers to cause a
denial of service (crash) via unspecified vectors, which triggers an
improper conversion between unsigned and signed types, leading to a buffer
overflow.
