  script_tag(name:"insight", value:"Tyler Hicks discovered that BusyBox incorrectly handled symlinks inside tar
archives. If a user or automated system were tricked into processing a
specially crafted tar archive, a remote attacker could overwrite arbitrary
files outside of the current directory. This issue only affected Ubuntu
14.04 LTS and Ubuntu 16.04 LTS. (CVE-2011-5325)

Mathias Krause discovered that BusyBox incorrectly handled kernel module
loading restrictions. A local attacker could possibly use this issue to
bypass intended restrictions. This issue only affected Ubuntu 14.04 LTS.
(CVE-2014-9645)

It was discovered that BusyBox incorrectly handled certain ZIP archives. If
a user or automated system were tricked into processing a specially crafted
ZIP archive, a remote attacker could cause BusyBox to crash, leading to a
denial of service. This issue only affected Ubuntu 14.04 LTS and Ubuntu
16.04 LTS. (CVE-2015-9261)

Nico Golde discovered that the BusyBox DHCP client incorrectly handled
certain malformed domain names. A remote attacker could possibly use this

arbitrary code. This issue only affected Ubuntu 14.04 LTS and Ubuntu 16.04
LTS. (CVE-2016-2148)

It was discovered that BusyBox incorrectly handled certain bzip2 archives.
If a user or automated system were tricked into processing a specially
crafted bzip2 archive, a remote attacker could cause BusyBox to crash,
leading to a denial of service, or possibly execute arbitrary code. This
issue only affected Ubuntu 14.04 LTS and Ubuntu 16.04 LTS. (CVE-2017-15873)

It was discovered that BusyBox incorrectly handled tab completion. A local
attacker could possibly use this issue to execute arbitrary code. This
issue only affected Ubuntu 14.04 LTS and Ubuntu 16.04 LTS. (CVE-2017-16544)
