CVE-2022-0529 [LOW] unzip vulnerabilities
Title: unzip vulnerabilities
Summary: Several security issues were fixed in unzip.
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)
It was discovered that unzip did not properly perform bounds checking while
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)

FAQ: Is Azure Linux the only Microsoft product that includes this open-source library and is therefore potentially affected by this vulnerability?
One of the main benefits to our customers who choose to use the Azure Linux distro is the commitment to keep it up to date with the most recent and most secure versions of the open source libraries with which the distro is composed. Microsoft is committed to transparency in this work which is why we began publishing CSAF/VEX in October 2025. See this blog post for more information. If impact to additional products is identified, we will update the CVE to reflect this.

A flaw was found in Unzip. The vulnerability occurs during the conversion of a wide string to a local string that leads to a heap of out-of-bound write. This flaw allows an attacker to input a specially crafted zip file, leading to a crash or code execution.
A flaw was found in Unzip. The vulnerability occurs during the conversion of a wide string to a local string that leads to a heap of out-of-bound write. This flaw allows an attacker to input a specially crafted zip file, leading to a crash.
Statement: This issue is classified with a low severity primarily because untrusted zip files are not typically extracted with the root user, limiting the impact of this issue. Additionally, this heap-based
