Subject: [PATCH xserver] xkb: Fix buffer overflow in XkbChangeTypesOfKey()
|
|
|
|
If XkbChangeTypesOfKey() is called with nGroups == 0, it will resize the
|
|
key syms to 0 but leave the key actions unchanged.
|
|
|
|
If later, the same function is called with a non-zero value for nGroups,
|
|
this will cause a buffer overflow because the key actions are of the wrong
|
|
size.
|
|
|
|
To avoid the issue, make sure to resize both the key syms and key actions
|
|
when nGroups is 0.
