The fix for CVE-2006-6332 in r1842 was not entirely correct. In
|
|
encode_ie() the bound check did not consider that each byte from
|
|
the IE causes two bytes to be written into buffer. That could
|
|
lead to a kernel oops, but does not allow code injection. This is
|
|
now fixed.
|
|
|
|
Due to the type of this problem it does not trigger another
|
|
urgent security bugfix release. v0.9.3 is at the door anyway.
