"This update for zziplib fixes the following issues :

Security issues fixed :

CVE-2018-16548: Avoid a memory leak from __zzip_parse_root_directory()
which could lead to denial of service. (bsc#1107424)

CVE-2018-7727: Fixed a memory leak in unzzip_cat() (bsc#1084515).

Non-security issue fixed: Prevented division by zero by first checking
if uncompressed size is 0. This may happen with directories which have
a compressed and uncompressed size of 0. (bsc#1129403)

Note that Tenable Network Security has extracted the preceding
description block directly from the SUSE security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues.");
