SynopsisThe remote Ubuntu host is missing one or more security-related patches.
DescriptionIt was discovered that LibVNCServer incorrectly handled certain packet lengths. A remote attacker able to connect to a LibVNCServer could possibly use this issue to obtain sensitive information, cause a denial of service, or execute arbitrary code.
Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
SolutionUpdate the affected libvncclient1, libvncserver0 and / or libvncserver1 packages.
