Description:	Summary: The remote host is missing an update for the Debian 'libarchive' package(s) announced via the DLA-661-1 advisory. Vulnerability Insight: Agostino Sarubbo of Gentoo discovered several security vulnerabilities in libarchive, a multi-format archive and compression library. An attacker could take advantage of these flaws to cause a buffer overflow or an out of bounds read using a carefully crafted input file. CVE-2016-8687 Agostino Sarubbo of Gentoo discovered a possible stack-based buffer overflow when printing a filename in bsdtar_expand_char() of util.c. CVE-2016-8688 Agostino Sarubbo of Gentoo discovered a possible out of bounds read when parsing multiple long lines in bid_entry() and detect_form() of archive_read_support_format_mtree.c. CVE-2016-8689 Agostino Sarubbo of Gentoo discovered a possible heap-based buffer overflow when reading corrupted 7z files in read_Header() of archive_read_support_format_7zip.c. For Debian 7 Wheezy, these problems have been fixed in version 3.0.4-3+wheezy5. We recommend that you upgrade your libarchive packages.
