Ubuntu 16.04 LTS / 18.04 LTS : unzip vulnerabilities (USN-4672-1)

high Nessus Plugin ID 144337

Synopsis

The remote Ubuntu host is missing one or more security updates.

Description

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.

- 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)

- Info-ZIP UnZip 6.0 has a buffer overflow in list.c, when a ZIP archive has a crafted relationship between the compressed-size value and the uncompressed-size value, because a buffer size is 10 and is supposed to be 12. (CVE-2018-18384)

- 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 mishandles the overlapping of files inside a ZIP container, leading to denial of service (resource consumption), aka a better zip bomb issue. (CVE-2019-13232)

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

Solution

Update the affected unzip package.
