xorg: xwayland: Buffer overflow in XkbChangeTypesOfKey()

A buffer overflow flaw was found in X.Org and Xwayland. If XkbChangeTypesOfKey is called with a 0 group, it will resize the key symbols table to 0 but leave the key actions unchanged. If the same function is later called with a non-zero value of groups, this will cause a buffer overflow because t...
