Denis Skvortsov discovered that xrdp, a Remote Desktop Protocol (RDP) server, was susceptible to an unauthenticated stack-based buffer overflow vulnerability, which may result in remote execution of arbitrary code.

For the oldstable distribution (bookworm), this problem has been fixed in version 0.9.21.1-1+deb12u2.
