CVE-2014-8240 is a vulnerability of currently unknown severity. Integer overflow in TigerVNC allows remote VNC servers to cause a denial of service (crash) and possibly execute arbitrary code via vectors related to screen size handling, which triggers a heap-based buffer overflow, a similar issue to CVE-2014-6051.. EPSS estimates a 3.55% chance of exploitation in the next 30 days.
