Title: zziplib vulnerabilities
Summary: zziplib could be made to crash or run programs as your login if it opened a
specially crafted file.
It was 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.
Instructions: In general, a standard system update will make all the necessary changes.

zziplib: Loading of misaligned memory address in zip.c:__zzip_fetch_disk_trailer can lead to a denial of service via crafted zip file
In ZZIPlib 0.13.67, there is a memory alignment error and bus error in the __zzip_fetch_disk_trailer function of zzip/zip.c. Remote attackers could leverage this vulnerability to cause a denial of service via a crafted zip file.
An unaligned memory access bug was found in the way ZZIPlib handled ZIP files. This flaw could potentially be used to crash the application using ZZIPlib by tricking the application into processing specially crafted ZIP files.

zziplib: improper fix for CVE-2018-6869 and CVE-2018-6484
It was discovered that the original fix for CVE-2018-6869 did not fully correct
CVE-2018-6484 and CVE-2018-6869. Function __zzip_fetch_disk_trailer uses signed
comparisons to check untrusted values which, in some configurations, are later
used in __zzip_parse_root_directory as parameter to mmap. Remote attackers
could leverage this vulnerability to cause a Denial of Service via a crafted
zip file.
