+Subject: [PATCH 01/51] Limit lenght to INT_MAX bytes in
+ rfbProcessFileTransferReadBuffer()
+
+This ammends 15bb719c03cc70f14c36a843dcb16ed69b405707 fix for a heap
+out-of-bound write access in rfbProcessFileTransferReadBuffer() when
+reading a transfered file content in a server. The former fix did not
+work on platforms with a 32-bit int type (expected by rfbReadExact()).

+Subject: [PATCH 50/51] LibVNCClient: Fix regression in Tight/Raw decoding
+
+Introduced by d7b1462 in LibVNCServer 0.9.12.  This regression caused
+the pixels in some RFB rectangles to become corrupted/garbled when the
+Tight encoding was used, without the JPEG subencoding, with a 15-bit or
+16-bit color depth.
+
+Fixes #335
+Fixes https://gitlab.com/Remmina/Remmina/issues/1824
