CVE-2014-6051 is a vulnerability of currently unknown severity. Integer overflow in the MallocFrameBuffer function in vncviewer.c in LibVNCServer 0.9.9 and earlier allows remote VNC servers to cause a denial of service (crash) and possibly execute arbitrary code via an advertisement for a large screen size, which triggers a heap-based buffer overflow.. EPSS estimates a 8.27% chance of exploitation in the next 30 days.
