overwrite arbitrary files. (CVE-2016-5418)

Christian Wressnegger, Alwin Maier, and Fabian Yamaguchi discovered that
libarchive incorrectly handled filename lengths when writing ISO9660
archives. A remote attacker could use this issue to cause libarchive to
crash, resulting in a denial of service, or possibly execute arbitrary
code. This issue only applied to Ubuntu 12.04 LTS, Ubuntu 14.04 LTS and
Ubuntu 16.04 LTS. (CVE-2016-6250)

Alexander Cherepanov discovered that libarchive incorrectly handled
recursive decompressions. A remote attacker could possibly use this issue
to cause libarchive to hang, resulting in a denial of service. This issue
only applied to Ubuntu 12.04 LTS, Ubuntu 14.04 LTS and Ubuntu 16.04 LTS.
(CVE-2016-7166)

It was discovered that libarchive incorrectly handled non-printable
multibyte characters in filenames. A remote attacker could possibly use
this issue to cause libarchive to crash, resulting in a denial of service.
(CVE-2016-8687)

It was discovered that libarchive incorrectly handled line sizes when
extracting certain archives. A remote attacker could possibly use this
issue to cause libarchive to crash, resulting in a denial of service.
(CVE-2016-8688)

It was discovered that libarchive incorrectly handled multiple EmptyStream
attributes when extracting certain 7zip archives. A remote attacker could
possibly use this issue to cause libarchive to crash, resulting in a denial
of service. (CVE-2016-8689)

Jakub Jirasek discovered that libarchive incorrectly handled memory when
extracting certain archives. A remote attacker could possibly use this
issue to cause libarchive to crash, resulting in a denial of service.
