Summary:

USN-2788-1 introduced a regression in unzip.

Software Description:

problem.

We apologize for the inconvenience.

protected archives. If a user or automated system were tricked into
processing a specially crafted zip archive, an attacker could possibly
execute arbitrary code. (CVE-2015-7696)
