+Subject: [PATCH 05/11] gwinhttpfile: Avoid arithmetic overflow when
+ calculating a size
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+The members of `URL_COMPONENTS` (`winhttp_file->url`) are `DWORD`s, i.e.
+32-bit unsigned integers. Adding to and multiplying them may cause them
+to overflow the unsigned integer bounds, even if the result is passed to
+`g_memdup2()` which accepts a `gsize`.
+
+Cast the `URL_COMPONENTS` members to `gsize` first to ensure that the
+arithmetic is done in terms of `gsize`s rather than unsigned integers.
+
+Spotted by Sebastian Dröge.
+
+Signed-off-by: Philip Withnall <pwithnall@endlessos.org>
+Helps: #2319
