RHEL 5 : unzip (Unpatched Vulnerability)

high Nessus Plugin ID 196625

Synopsis

The remote Red Hat 5 host is affected by multiple vulnerabilities that will not be patched.

Description

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)

- 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)

- 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 these issues but has instead relied on the package manager's report that the package is installed.

Solution

The vendor has acknowledged the vulnerabilities but no solution has been provided. Refer to the vendor for remediation guidance.
