    It was discovered that libarchive incorrectly handled hardlink entries when extracting archives. A remote
    attacker could possibly use this issue to 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. (CVE-2017-5601)
