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.

An update of the unzip package has been released.

There are packages installed that are affected by multiple vulnerabilities referenced in the following CVEs:

  - 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)

  - 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)

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - 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 relies on the presence of the package as reported by the vendor.

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-2015-7696 advisory.

  - 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 this issue but has instead relied only on the application's self-reported version number.

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

  - 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)

  - 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)

Gustavo Grieco reports :

Two issues were found in unzip 6.0 :

* A heap overflow triggered by unzipping a file with password (e.g unzip -p -P x sigsegv.zip).

* A denegation of service with a file that never finishes unzipping (e.g. unzip sigxcpu.zip).

Two vulnerabilities have been found in unzip, a de-archiver for .zip files. The Common Vulnerabilities and Exposures project identifies the following problems :

  - CVE-2015-7696     Gustavo Grieco discovered that unzip incorrectly handled     certain password protected archives. If a user or     automated system were tricked into processing a     specially crafted zip archive, an attacker could     possibly execute arbitrary code.

  - CVE-2015-7697     Gustavo Grieco discovered that unzip incorrectly handled     certain malformed archives. If a user or automated     system were tricked into processing a specially crafted     zip archive, an attacker could possibly cause unzip to     hang, resulting in a denial of service.

The remote Ubuntu 14.04 LTS host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-2788-1 advisory.

    Gustavo Grieco discovered that unzip incorrectly handled certain password protected archives. If a user or     automated system were tricked into processing a specially crafted zip archive, an attacker could possibly     execute arbitrary code. (CVE-2015-7696)

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

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

Gustavo Grieco discovered with a fuzzer that unzip was vulnerable to a heap overflow and to a denial of service with specially crafted password-protected ZIP archives.

For the Debian 6 squeeze, these issues haven been fixed in unzip 6.0-4+deb6u3.
