+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.
