CVE-2014-0011 is a critical-severity vulnerability rated 9.8/10 on the CVSS scale. Multiple heap-based buffer overflows in the ZRLE_DECODE function in common/rfb/zrleDecode.h in TigerVNC before 1.3.1, when NDEBUG is enabled, allow remote VNC servers to cause a denial of service (vncviewer crash) and possibly execute arbitrary code via vectors related to screen image rendering.. EPSS estimates a 2.49% chance of exploitation in the next 30 days.
