The zzip_mem_entry_extra_block function in memdisk.c in zziplib 0.13.62 allows remote attackers to cause a denial of service (invalid memory read and crash) via a crafted ZIP file.

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.
