A flaw was found in gnome-remote-desktop as shipped in Red Hat Enterprise Linux. In the VNC TLS I/O handlers, retryable GnuTLS results (GNUTLS_E_AGAIN and GNUTLS_E_INTERRUPTED) are handled with an unbounded busy loop instead of yielding to the event loop. A remote attacker who can reach an enabled VNC TLS listener can cause the event-loop thread to spin at high CPU with no forward progress, resulting in denial of service.

Fixes

Solution

No solution given by the vendor.


Workaround

If VNC is not required, disable the gnome-remote-desktop VNC service. If it must remain enabled, restrict the VNC listener to trusted hosts or management networks using host-based firewall rules.
