Public bug reported:
After recent system updates on Ubuntu 24.04 (Noble), GNOME Remote
Desktop (RDP) began crashing immediately upon client connection.
The issue appears to be caused by an update to the FreeRDP / WinPR
libraries.
Observed behavior:
- RDP connection initiates successfully
- Capability negotiation begins (CLIPRDR, RDPGFX, audio)
- gnome-remote-desktop daemon crashes with memory errors:
- "corrupted size vs. prev_size"
- segmentation fault (SEGV)
- service restarts repeatedly via systemd
This makes RDP unusable.
Affected versions
gnome-remote-desktop: 46.3-0ubuntu1.2
libfreerdp3-3: 3.5.1+dfsg1-0ubuntu1.4
libfreerdp-server3-3: 3.5.1+dfsg1-0ubuntu1.4
libfreerdp-client3-3: 3.5.1+dfsg1-0ubuntu1.4
libwinpr3-3: 3.5.1+dfsg1-0ubuntu1.4
Logs (example)
gnome-remote-desktop-daemon: corrupted size vs. prev_size
systemd: Main process exited, code=dumped, status=11/SEGV
gnome-remote-desktop.service: Failed with result 'core-dump'
System was previously working prior to updates on 2026-03-19.
dpkg logs show upgrade:
libfreerdp3-3: 3.5.1+dfsg1-0ubuntu1.2 → 3.5.1+dfsg1-0ubuntu1.4
libwinpr3-3: same version bump
Issue began immediately after this update.
Workaround
Downgrading FreeRDP / WinPR libraries restores functionality completely.
Command used:
sudo apt install --allow-downgrades \
libfreerdp3-3=3.5.0+dfsg1-0ubuntu1 \
libfreerdp-server3-3=3.5.0+dfsg1-0ubuntu1 \
libfreerdp-client3-3=3.5.0+dfsg1-0ubuntu1 \
libwinpr3-3=3.5.0+dfsg1-0ubuntu1
After downgrade:
- No crashes
- RDP negotiation succeeds
- Service remains stable
This strongly suggests a regression in FreeRDP 3.5.1-0ubuntu1.4 or its
interaction with gnome-remote-desktop.
- Breaks all GNOME RDP access
- Affects multiple machines (Latitude 7420, Optiplex)
- Requires manual downgrade to restore functionality
track when Ubuntu releases the patch so you can safely un-hold the
packages
