"If a ZIP archive contains binaries with the setuid and/or setgid bit
set, unzip preserved those bits when extracting the archive. This
could be exploited by tricking the administrator into unzipping an
archive with a setuid-root binary into a directory the attacker can
access. This allowed the attacker to execute arbitrary commands with
root privileges.

The updated version does not preserve setuid, setgid, and sticky bits
any more by default. The old behaviour can be explicitly requested now
by supplying the option '-K'.

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