Descriptions
A out-of-bounds write flaw was found in the xorg-x11-server. This issue occurs due to an incorrect calculation of a buffer offset when copying data stored in the heap in the XIChangeDeviceProperty function in Xi/xiproperty.c and in RRChangeOutputProperty function in randr/rrproperty.c, allowing for possible escalation of privileges or denial of service.
Se encontró una falla de escritura fuera de los límites en el servidor xorg-x11. Este problema ocurre debido a un cálculo incorrecto de un desplazamiento del búfer al copiar datos almacenados en el montón en la función XIChangeDeviceProperty en Xi/xiproperty.c y en la función RRChangeOutputProperty en randr/rrproperty.c, lo que permite una posible escalada de privilegios o Denegación de Servicio (DoS). .
This vulnerability allows local attackers to escalate privileges on affected installations of X.Org Server. An attacker must first obtain the ability to execute low-privileged code on the target system in order to exploit this vulnerability.
The specific flaw exists within the XIChangeDeviceProperty function. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a heap-based buffer. An attacker can leverage this vulnerability to escalate privileges and execute arbitrary code in the context of root.
