AlmaLinux 9.2 [TuxCare] Security Update: gnome-remote-desktop (ALMALINUX9.2:CLSA-2026:1794007006)

high Nessus Plugin ID 377136

Synopsis

The AlmaLinux host is missing one or more security updates.

Description

The AlmaLinux 9.2 host has a package installed that is affected by a vulnerability as referenced in the TuxCare ALMALINUX9.2:CLSA-2026:1794007006 advisory.

 - 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. (CVE-2026-109832)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Update the affected gnome-remote-desktop package based on the guidance in TuxCare advisory ALMALINUX9.2:CLSA-2026:1794007006.
