Security update for LibVNCServer

Notes

Title of the patch
Security update for LibVNCServer
Description of the patch
LibVNCServer was updated to fix two security issues. These security issues were fixed: - CVE-2016-9941: Heap-based buffer overflow in rfbproto.c allowed remote servers to cause a denial of service (application crash) or possibly execute arbitrary code via a crafted FramebufferUpdate message containing a subrectangle outside of the client drawing area (bsc#1017711) - CVE-2016-9942: Heap-based buffer overflow in ultra.c allowed remote servers to cause a denial of service (application crash) or possibly execute arbitrary code via a crafted FramebufferUpdate message with the Ultra type tile, such that the LZO payload decompressed length exceeds what is specified by the tile dimensions (bsc#1017712)
