The rfbSendFramebufferUpdate function in server/libvncserver/rfbserver.c in
vino-server in Vino 2.x before 2.28.3, 2.32.x before 2.32.2, 3.0.x before
3.0.2, and 3.1.x before 3.1.1, when raw encoding is used, allows remote
authenticated users to cause a denial of service (daemon crash) via a large
(1) X position or (2) Y position value in a framebuffer update request that
triggers an out-of-bounds memory access, related to the rfbTranslateNone
and rfbSendRectEncodingRaw functions.
