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.
