Buffer overflow in UnZip 5.50 and earlier allows user-assisted attackers to execute arbitrary code via a long filename command line argument. NOTE: since the overflow occurs in a non-setuid program, there are not many scenarios under which it poses a vulnerability, unless unzip is passed long arguments when it is invoked from other programs.

The CentOS Linux 7.9 host has a package installed that is affected by multiple vulnerabilities as referenced in the CIQ ciqsa-2026_1650 advisory.

    This advisory aggregates security fixes for the unzip SRPM in CIQ CentOS Bridge 7.9. It addresses 9 CVEs:
    CVE-2019-13232, CVE-2018-1000035, CVE-2005-4667, CVE-2008-0888, CVE-2014-8139, and 4 more.

Tenable has extracted the preceding description block directly from the CIQ security advisory.

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

From Red Hat Security Advisory 2007:0203 :

Updated unzip packages that fix two security issues and various bugs are now available.

This update has been rated as having low security impact by the Red Hat Security Response Team.

The unzip utility is used to list, test, or extract files from a zip archive.

A race condition was found in Unzip. Local users could use this flaw to modify permissions of arbitrary files via a hard link attack on a file while it was being decompressed (CVE-2005-2475)

A buffer overflow was found in Unzip command line argument handling.
If a user could be tricked into running Unzip with a specially crafted long file name, an attacker could execute arbitrary code with that user's privileges. (CVE-2005-4667)

As well, this update adds support for files larger than 2GB.

All users of unzip should upgrade to these updated packages, which contain backported patches that resolve these issues.

If a user could be tricked into running Unzip with a specially crafted long file name, an attacker could execute arbitrary code with that user's privileges. (CVE-2005-4667)

A buffer overflow in the command line argument parsing has been discovered in unzip, the de-archiver for ZIP files, that could lead to the execution of arbitrary code.

A buffer overflow was discovered in the handling of file name arguments. By tricking a user or automated system into processing a specially crafted, excessively long file name with unzip, an attacker could exploit this to execute arbitrary code with the user's privileges.

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

A buffer overflow was foiund in how unzip handles file name arguments.
If a user could tricked into processing a specially crafted, excessively long file name with unzip, an attacker could execute arbitrary code with the user's privileges.

The updated packages have been patched to address this issue.
