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.

  - zziplib: uncontrolled memory allocation in __zzip_parse_root_directory in zzip/zip.c (CVE-2018-6869)

  - Heap-based buffer overflow in the __zzip_get32 function in fetch.c in zziplib 0.13.62, 0.13.61, 0.13.60,     0.13.59, 0.13.58, 0.13.57, 0.13.56 allows remote attackers to cause a denial of service (crash) via a     crafted ZIP file. (CVE-2017-5974)

  - Heap-based buffer overflow in the __zzip_get64 function in fetch.c in zziplib 0.13.62, 0.13.61, 0.13.60,     0.13.59, 0.13.58, 0.13.57, 0.13.56 allows remote attackers to cause a denial of service (crash) via a     crafted ZIP file. (CVE-2017-5975)

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 Ubuntu 14.04 LTS / 16.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-3320-1 advisory.

    Agostino Sarubbo discovered that zziplib incorrectly handled certain malformed ZIP files. If a user or     automated system were tricked into opening a specially crafted ZIP file, a remote attacker could cause     zziplib to crash, resulting in a denial of service, or possibly execute arbitrary code.

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.
