title: Xorg-x11-server: out-of-bounds write in xichangedeviceproperty/rrchangeoutputproperty
description: 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.
problem types: Out-of-bounds Write
