-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA256 - ------------------------------------------------------------------------- Debian Security Advisory DSA-6469-1 security@debian.org https://www.debian.org/security/ Aron Xu August 27, 2026 https://www.debian.org/security/faq - ------------------------------------------------------------------------- Package : xrdp CVE ID : CVE-2026-32105 CVE-2026-32107 CVE-2026-32623 CVE-2026-32624 CVE-2026-33145 CVE-2026-33516 CVE-2026-33689 CVE-2026-35512 CVE-2026-41252 CVE-2026-41521 CVE-2026-42218 CVE-2026-44178 CVE-2026-44978 CVE-2026-54538 CVE-2026-55238 CVE-2026-55639 CVE-2026-55645 Debian Bug : 1134339 Multiple vulnerabilities were discovered in xrdp, a Remote Desktop Protocol (RDP) server, which may result in denial of service, information disclosure, privilege escalation or the execution of arbitrary code. Several of these issues are exploitable by an unauthenticated remote attacker. This update also changes two defaults, as part of the fixes: * Alternate shells supplied by the client are now rejected unless AllowAlternateShell is explicitly enabled in /etc/xrdp/sesman.ini. This is the fix for CVE-2026-33145 and applies even on systems with a locally modified sesman.ini. * The generic VNC proxy session type [vnc-any] is now commented out in /etc/xrdp/xrdp.ini. It was reachable before authentication and exposed CVE-2026-41252 and CVE-2026-41521 to unauthenticated clients. Administrators who need it should re-enable it and restrict it to specific hosts and ports. For the stable distribution (trixie), these problems have been fixed in version 0.10.1-3.1+deb13u2. We recommend that you upgrade your xrdp packages.
