It was discovered that unzip did not properly handle unicode strings under
certain circumstances. If a user were tricked into opening a specially crafted
zip file, an attacker could possibly use this issue to cause unzip to crash,
resulting in a denial of service, or possibly execute arbitrary code.
(CVE-2021-4217)

converting wide strings to local strings. If a user were tricked into opening a
specially crafted zip file, an attacker could possibly use this issue to cause
unzip to crash, resulting in a denial of service, or possibly execute arbitrary
code. (CVE-2022-0529, CVE-2022-0530)
