Description Pierre Ossman cendio 2016-08-16 15:07:46 CEST
There is a bug in FLTK that causes vncviewer on Windows to crash when it receives clipboard data containing CRLF line endings[1]. The problem is a bad for loop that causes buffer overflows.

[1] These are technically a RFB protocol violation, but we are not filtering or enforcing this properly
Comment 3 Henrik Andersson cendio 2016-08-17 16:32:11 CEST
Verified that chavez builds out client with fltk-1.3.3-8
Comment 4 Henrik Andersson cendio 2016-08-18 09:59:04 CEST
Verified that i could reproduce the crash with 4.6.0 client and that it clipboard is working as expected using build 5208 on the windows platform.
