Subject: [PATCH] CVE-2017-11541: In safeputs(), check the length before
|
||||
checking for a NUL terminator.
|
||||
|
||||
safeputs() doesn't do packet bounds checking of its own; it assumes that
|
||||
the caller has checked the availability in the packet data of all maxlen
|
||||
bytes of data. This means we should check that we're within the
|
||||
specified limit before looking at the byte.
|
||||
|
||||
This fixes a buffer over-read discovered by Kamil Frankowicz.
|
||||
|
||||
Add a test using the capture file supplied by the reporter(s).

Report if it's not, and don't use it as an out-of-bounds index into an

array.
