CVE-2017-5885 (opens in a new tab)How to fix?
Upgrade Alpine:3.20 gtk-vnc to version 0.7.0-r0 or higher.
NVD Description
Note: Versions mentioned in the description apply only to the upstream gtk-vnc package and not the gtk-vnc package as distributed by Alpine.
See How to fix? for Alpine:3.20 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.
