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.

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

  - Buffer overflow in the list_files function in list.c in     Info-Zip UnZip 6.0 allows remote attackers to cause a     denial of service (crash) via vectors related to the     compression method.(CVE-2014-9913)

  - 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)

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-2014-9913 advisory.

  - Buffer overflow in the list_files function in list.c in Info-Zip UnZip 6.0 allows remote attackers to     cause a denial of service (crash) via vectors related to the compression method. (CVE-2014-9913)

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 6 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)

  - Buffer overflow in the list_files function in list.c in Info-Zip UnZip 6.0 allows remote attackers to     cause a denial of service (crash) via vectors related to the compression method. (CVE-2014-9913)

  - Info-ZIP UnZip 6.0 allows remote attackers to cause a denial of service (heap-based buffer over-read and     application crash) or possibly execute arbitrary code via a crafted password-protected ZIP archive,     possibly related to an Extra-Field size value. (CVE-2015-7696)

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 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)

  - Buffer overflow in the list_files function in list.c in Info-Zip UnZip 6.0 allows remote attackers to     cause a denial of service (crash) via vectors related to the compression method. (CVE-2014-9913)

  - Info-ZIP UnZip 6.0 allows remote attackers to cause a denial of service (heap-based buffer over-read and     application crash) or possibly execute arbitrary code via a crafted password-protected ZIP archive,     possibly related to an Extra-Field size value. (CVE-2015-7696)

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

'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.

An update of the unzip package has been released.

The remote Ubuntu 16.04 LTS / 18.04 LTS host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-4672-1 advisory.

    Rene Freingruber discovered that unzip incorrectly handled certain specially crafted password protected     ZIP archives. If a user or automated system using unzip were tricked into opening a specially crafted zip     file, an attacker could exploit this to cause a crash, resulting in a denial of service.
    (CVE-2018-1000035)

    Antonio Carista discovered that unzip incorrectly handled certain specially crafted ZIP archives. If a     user or automated system using unzip were tricked into opening a specially crafted zip file, an attacker     could exploit this to cause a crash, resulting in a denial of service. This issue only affected Ubuntu     12.04 ESM and Ubuntu 14.04 ESM. (CVE-2018-18384)

    It was discovered that unzip incorrectly handled certain specially crafted ZIP archives.
