CVE-2026-44988

LibVNCClient is a library for easy implementation of a VNC client. In 0.9.15 and earlier, LibVNCClient's Tight encoding decoder uses fixed-size 2048-pixel scratch buffers for the Gradient filter, but it does not reject Tight rectangles whose width is larger than 2048 pixels. A malicious VNC serve...

OESA-2026-2565 libvncserver security update

libvncserver is a set of programs using the RFB Remote Frame Buffer protocol. They are designed to "export" a frame buffer via net: you set up a server and can connect to it via VNC viewers. If the server supports WebSockets which LibVNCServer does, you can also connect using an in-browser VNC...
