A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 18.10 - Ubuntu 18.04 LTS - Ubuntu 16.04 LTS - Ubuntu 14.04 LTS

Summary:

Several security issues were fixed in BusyBox.

Software Description: - busybox: Tiny utilities for small and embedded systems

Details:

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 issue to cause the DHCP client to crash, leading to a denial of service. This issue only affected Ubuntu 14.04 LTS and Ubuntu 16.04 LTS. (CVE-2016-2147)

Nico Golde discovered that the BusyBox DHCP client incorrectly handled certain 6RD options. A remote attacker could use this issue to cause the DHCP client 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-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)

It was discovered that the BusyBox wget utility incorrectly handled certain responses. A remote attacker could use this issue to cause BusyBox to crash, resulting in a denial of service, or possibly execute arbitrary code. (CVE-2018-1000517)

It was discovered that the BusyBox DHCP utilities incorrectly handled certain memory operations. A remote attacker could possibly use this issue to access sensitive information. (CVE-2018-20679, CVE-2019-5747)
