Hi Daniel, thanks for this regression report. On Mo 30 Dez 2019 14:01:04 CET, Daniel Reichelt wrote:
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
Does this upstream commit being added to the patches in +deb10u2 fix your issue?
https://github.com/LibVNC/libvncserver/commit/7e63df224aa45a8b541cd63a870594454aba7526.patch Could you test this?
