Package: unp
Version: 1.0.12
Severity: important
Tags: security

unp doesn't escape filenames properly. Try this:

touch empty
zip \`ls\`.zip empty
unp \`ls\`.zip

and it will give you a directory listing.

This means that any application using 'unp' for a generic decompression
utility might be vulnerable to a filename-based injection attack.

Maybe increase the severity level?
