This vulnerability could possibly lead to arbitrary code execution.

Does the unzip-archlinux version contain this patch too?

As far as I can tell, our version is not impacted because we use the 6.0 info-zip (not the 6.10 beta) _and_ we do not apply the vulnerable "06-unzip60-alt-iconv-utf8" patch.
