Descriptions
Xenstore: Guests can crash xenstored Due to a bug in the fix of XSA-115 a malicious guest can cause xenstored to use a wrong pointer during node creation in an error path, resulting in a crash of xenstored or a memory corruption in xenstored causing further damage. Entering the error path can be controlled by the guest e.g. by exceeding the quota value of maximum nodes per domain.
Xenstore: Los invitados pueden bloquear xenstored Debido a un error en la solución de XSA-115, un invitado malintencionado puede hacer que xenstored use un puntero incorrecto durante la creación del nodo en una ruta de error, lo que resulta en una falla de xenstored o una corrupción de la memoria en xenstored, lo que provoca más daño. El invitado puede controlar el ingreso de la ruta de error, por ejemplo, excediendo el valor de cuota de nodos máximos por dominio.
