Security issue fixed:

- CVE-2020-18770: Fixed denial-of-service in function zzip_disk_entry_to_file_header in mmapped.c (bsc#1214577).

Tenable has extracted the preceding description block directly from the SUSE security advisory.

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