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.
