-Subject: [PATCH] CVE-2017-11543/Make sure the SLIP direction octet is valid.
-
-Report if it's not, and don't use it as an out-of-bounds index into an
-array.
-
-This fixes a buffer overflow discovered by Wilfried Kirsch.
-
-Add a test using the capture file supplied by the reporter(s), modified
-so the capture file won't be rejected as an invalid capture.
