-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()).
