-Subject: [PATCH 2/5] EAP-pwd server: Fix payload length validation for Commit
- and Confirm
-
-The length of the received Commit and Confirm message payloads was not
-checked before reading them. This could result in a buffer read
-overflow when processing an invalid message.
-
-Fix this by verifying that the payload is of expected length before
-processing it. In addition, enforce correct state transition sequence to
-make sure there is no unexpected behavior if receiving a Commit/Confirm
-message before the previous exchanges have been completed.
-
-Thanks to Kostya Kortchinsky of Google security team for discovering and
-reporting this issue.
