CVE-2018-6381 zziplib vulnerabilities
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.

CVE-2018-7726 zziplib: Bus error in zip.c:__zzip_parse_root_directory() cause crash via crafted zip file
ZZIPlib through version 0.13.68 does not correctly validate input values used in
zip.c:__zzip_parse_root_directory() as parameters to mmap. Remote attackers
could leverage this vulnerability to cause a Denial of Service via a crafted
zip file.

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.
