NVD Description
Note: Versions mentioned in the description apply only to the upstream gvncpulse-devel package and not the gvncpulse-devel package as distributed by RHEL.
See How to fix? for RHEL:7 relevant fixed versions and status.
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.
