A flaw was found in unzip. The vulnerability occurs due to improper handling of Unicode strings, which can lead to a null pointer dereference. This flaw allows an attacker to input a specially crafted zip file, leading to a crash or code execution.

According to the versions of the unzip package installed, the EulerOS Virtualization installation on the remote host is affected by the following vulnerabilities :

  - A flaw was found in unzip. The vulnerability occurs due to improper handling of Unicode strings, which can     lead to a null pointer dereference. This flaw allows an attacker to input a specially crafted zip file,     leading to a crash or code execution. (CVE-2021-4217)

Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2023-2023-029 advisory.

  - A flaw was found in unzip. The vulnerability occurs due to improper handling of Unicode strings, which can     lead to a null pointer dereference. This flaw allows an attacker to input a specially crafted zip file,     leading to a crash or code execution. (CVE-2021-4217)

  - 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. (CVE-2022-0529, CVE-2022-0530)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

The version of unzip installed on the remote host is prior to 6.0-57. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2-2023-1906 advisory.
