libarchive: fix CVE-2013-0211
CVE description: 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. http://web.nvd.nist.gov/view/vuln/detail?vulnId=CVE-2013-0211 Signed-off-by: Baogen Shang <baogen.shang@windriver.com> Signed-off-by: Jeff Polk <jeff.polk@windriver.com> Signed-off-by: Hongxu Jia <hongxu.jia@windriver.com> Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>
