zziplib 0.13.62 allows remote attackers to cause a denial of service
(crash) via a crafted ZIP file.

- CVE-2017-5976 (arbitrary code execution)

Heap-based buffer overflow in the zzip_mem_entry_extra_block function
in memdisk.c in zziplib 0.13.62 allows remote attackers to cause a
denial of service (crash) via a crafted ZIP file.

- CVE-2017-5979 (denial of service)

The prescan_entry function in fseeko.c in zziplib 0.13.62 allows remote
