CVE-2017-5885 is a vulnerability of currently unknown severity. 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.. EPSS estimates a 4.98% chance of exploitation in the next 30 days.
