Hi all, the new use-after-free patches introduced in 0.9.11+dfsg-1.3~deb10u2 hurt connections to servers provided by x11vnc.
Previously, a server initiated by x11vnc -nopw -auth guess -display :0 -forever was perfectly fine to connect to using tightvncviewer. Now, with ~deb10u2, the remote windows of tightvncviewer comes up for a fraction of a second and then immediately closes with the message "Unknown encoding". Nothing changed on the involved systems besides libvncserver1/libvncclient1. Reverting only the use-after-free patches, re-building libvncserver1 and starting x11vnc using that package, tightvncviewer can connect again. Also, this issue does NOT appear when libvncserver1/testing (0.9.12+dfsg-5) is installed. Cheers Daniel
