Summary
[none]
Details

XKB Buffer overflow in CheckKeyTypes(). The function CheckKeyTypes() will loop over the client's request but won't perform any additional bound checking to ensure that the data read remains within the request bounds. As a result, a specifically crafted request may cause CheckKeyTypes() to read uninitialised memory past the request data.
