Amazon Linux 2023 Security Advisory: ALAS2023-2026-3393
Advisory Released Date: 2026-11-09
Advisory Updated Date: 2026-11-09
Severity:
Important
Issue Overview:
A denial-of-service flaw was found in gnome-remote-desktop. An unauthenticated remote attacker can open RDP connections without completing the handshake and retain the connection-throttling slots indefinitely because no pre-authentication handshake deadline is enforced. By exhausting the global connection limit, an attacker can prevent new RDP clients from connecting until a holding socket is closed. (CVE-2026-96541)
Affected Packages:
gnome-remote-desktop
Issue Correction:
Run dnf update gnome-remote-desktop --releasever 2023.12.20261109 or dnf update --advisory ALAS2023-2026-3393 --releasever 2023.12.20261109 to update your system.
