Summary
libvncserver security update
Details

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 viewer like noVNC. It is already in wide use for administration, but it is not that easy to program a server yourself.

Security Fix(es):

libvncclient v0.9.13 was discovered to contain a memory leak via the function rfbClientCleanup().(CVE-2020-29260)
