Subject: [PATCH xserver] xkb: fix some possible memleaks in XkbGetKbdByName
|
||||
|
||||
GetComponentByName returns an allocated string, so let's free that if we
|
||||
fail somewhere.

Subject: [PATCH xserver] xkb: proof GetCountedString against request length
|
||||
attacks
|
||||
|
||||
GetCountedString did a check for the whole string to be within the
|
||||
request buffer but not for the initial 2 bytes that contain the length
|
||||
field. A swapped client could send a malformed request to trigger a
|
||||
swaps() on those bytes, writing into random memory.
