xorg: xwayland: Use-after-free in SyncInitTrigger()

A use-after-free flaw was found in X.Org and Xwayland. When changing an alarm, the values of the change mask are evaluated one after the other, changing the trigger values as requested, and eventually, SyncInitTrigger is called. If one of the changes triggers an error, the function will return...

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...
