High impact if exploited, but EPSS currently rates exploitation as unlikely (4.98%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
Multiple integer overflows in the (1) vnc_connection_server_message and (2) vnc_color_map_set functions in gtk-vnc before 0.7.0 allow remote servers to cause a denial of service (crash) or possibly execute arbitrary code via vectors involving SetColorMapEntries, which triggers a buffer overflow.
