It was discovered that BusyBox incorrectly handled certain malformed gzip
archives. If a user or automated system were tricked into processing a
specially crafted gzip archive, a remote attacker could use this issue to
cause BusyBox to crash, resulting in a denial of service, or execute
arbitrary code. This issue only affected Ubuntu 14.04 LTS.
(CVE-2021-28831)

It was discovered that BusyBox did not properly validate user input when
performing certain arithmetic operations. If a user or automated system
were tricked into processing a specially crafted file, an attacker could
possibly use this issue to cause BusyBox to crash, resulting in a denial
of service, or execute arbitrary code. (CVE-2022-48174)
