Astra Linux – Vulnerability in libvncserver

LibVNCClient is a library for easy implementation of a VNC client. In versions 0.9.15 and earlier, LibVNCClient’s Tight encoding decoder used fixed-size 2048-pixel scratch buffers for the Gradient filter. However, it did not reject Tight rectangles whose width exceeded 2048 pixels. A malicious VN...
