Buffer overflow in the zi_short function in zipinfo.c in Info-Zip UnZip 6.0 allows remote attackers to cause a denial of service (crash) via a large compression method value in the central directory file header.

An update of the unzip package has been released.

The version of unzip installed on the remote CBL Mariner 2.0 host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the CVE-2016-9844 advisory.

  - Buffer overflow in the zi_short function in zipinfo.c in Info-Zip UnZip 6.0 allows remote attackers to     cause a denial of service (crash) via a large compression method value in the central directory file     header. (CVE-2016-9844)

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

The remote Redhat Enterprise Linux 7 host has one or more packages installed that are affected by multiple vulnerabilities that have been acknowledged by the vendor but will not be patched.

  - unzip: Heap-based buffer overflow in fileio.c:UzpPassword function allows code execution     (CVE-2018-1000035)

Note that Nessus has not tested for these issues but has instead relied on the package manager's report that the package is installed.

The remote Redhat Enterprise Linux 5 host has one or more packages installed that are affected by multiple vulnerabilities that have been acknowledged by the vendor but will not be patched.

  - unzip: Heap-based buffer overflow in fileio.c:UzpPassword function allows code execution     (CVE-2018-1000035)

  - Heap-based buffer overflow in the CRC32 verification in Info-ZIP UnZip 6.0 and earlier allows remote     attackers to execute arbitrary code via a crafted zip file in the -t command argument to the unzip     command. (CVE-2014-8139)

  - Heap-based buffer overflow in the test_compr_eb function in Info-ZIP UnZip 6.0 and earlier allows remote     attackers to execute arbitrary code via a crafted zip file in the -t command argument to the unzip     command. (CVE-2014-8140)

Note that Nessus has not tested for these issues but has instead relied on the package manager's report that the package is installed.

This plugin has been deprecated as it does not adhere to established standards for this style of check.

The version of unzip installed on the remote host is prior to 6.0-43. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2-2021-1604 advisory.

    Info-ZIP UnZip 6.0 allows remote attackers to cause a denial of service (infinite loop) via empty bzip2     data in a ZIP archive. (CVE-2015-7697)

    Buffer overflow in the zi_short function in zipinfo.c in Info-Zip UnZip 6.0 allows remote attackers to     cause a denial of service (crash) via a large compression method value in the central directory file     header. (CVE-2016-9844)

    A heap-based buffer overflow exists in Info-Zip UnZip version <= 6.00 in the processing of password-     protected archives that allows an attacker to perform a denial of service or to possibly achieve code     execution. (CVE-2018-1000035)

Security fix for CVE-2016-9844

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

'unzip -l' (CVE-2014-9913) and 'zipinfo' (CVE-2016-9844) were vulnerable to buffer overflows when provided malformed or maliciously-crafted ZIP files.

For Debian 7 'Wheezy', these problems have been fixed in version 6.0-8+deb7u6.

We recommend that you upgrade your unzip packages.
