Package : libarchive
Version : 3.0.4-3+wheezy5
CVE ID : CVE-2016-8687 CVE-2016-8688 CVE-2016-8689
Debian Bug : 840934 840935 840936
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.
