Descriptions
The scp_v0s_accept function in sesman/libscp/libscp_v0.c in the session manager in xrdp through 0.9.4 uses an untrusted integer as a write length, which allows local users to cause a denial of service (buffer overflow and application crash) or possibly have unspecified other impact via a crafted input stream.
La función scp_v0s_accept en sesman/libscp/libscp_v0.c en el administrador de sesión en xrdp hasta la versión 0.9.4 emplea un entero no fiable como longitud de escritura. Esto permite que usuarios locales provoquen una denegación de servicio (desbordamiento de búfer y cierre inesperado de la aplicación) o que, posiblemente, causen otro impacto sin especificar mediante un flujo de entrada manipulado.
