Security researcher Ronald Crane reported five moderate rated vulnerabilities affecting released code that were found through code inspection. These included the following issues in WebRTC: an integer underflow, a missing status check, race condition, and a use of deleted pointers to create new object. A race condition in LibVPX was also identified. These do not all have clear mechanisms to be exploited through web content but are vulnerable if a mechanism can be found to trigger them.
