-Subject: [PATCH] Reject overflows of zip header fields in minizip.
-
-This checks the lengths of the file name, extra field, and comment
-that would be put in the zip headers, and rejects them if they are
-too long. They are each limited to 65535 bytes in length by the zip
-format. This also avoids possible buffer overflows if the provided
-fields are too long.
