A security issue affects these releases of Ubuntu and its derivatives:

Summary

Software description

Details
William Robinet discovered that unzip incorrectly handled certain
malformed zip archives. If a user or automated system were tricked into
processing a specially crafted zip archive, an attacker could possibly
execute arbitrary code.
