If your application is used in open networks or there are untrusted nodes in the network it is highly recommended to apply the patch. The problem was patched with commit 2324bcd5ba12cf28f47357a8f03cd41b7c04c52b As a workaround changes of commit 2324bcd5ba12cf28f47357a8f03cd41b7c04c52b can be applied to older versions."},{"lang":"es","value":"En ACCEL-PPP (una implementación de PPTP/PPPoE/L2TP/SSTP), se presenta un desbordamiento del búfer cuando se recibe un paquete de control l2tp con un AVP cuyo tipo es una cadena y no indicadores ocultos, la longitud se establece en menos de 6. Si su aplicación es usada en redes abiertas o existen nodos que no son confiables en la red, se recomienda aplicar el parche.
