CVE-2026-44988 LibVNCClient Tight Gradient decoding allows malicious server-triggered heap/stack OOB writes

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...
