CVE-2014-8240
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.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (3.55%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
