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 or possibly execute arbitrary code via a crafted FramebufferUpdate message containing a subrectangle outside of the client drawing area - CVE-2016-9942: Heap-based buffer overflow in ultra.c allowed remote servers to cause a denial of service 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
