-Subject: [PATCH 4/5] EAP-pwd server: Fix Total-Length parsing for fragment
- reassembly
-
-The remaining number of bytes in the message could be smaller than the
-Total-Length field size, so the length needs to be explicitly checked
-prior to reading the field and decrementing the len variable. This could
-have resulted in the remaining length becoming negative and interpreted
-as a huge positive integer.
-
-In addition, check that there is no already started fragment in progress
-before allocating a new buffer for reassembling fragments. This avoid a
-potential memory leak when processing invalid message.
