Security researcher Ronald Crane reported three vulnerabilities affecting released code that were found through code inspection. These include a high rated memory safety issue in the ANGLE graphics library, a moderate rated potential wild pointer flaw when handling zip files, and a critical rated integer overflow during metadata parsing in Mozilla's use of the libstagefright library.
The first two issues do not all have clear mechanisms to be exploited through web content but are vulnerable if a mechanism can be found to trigger them. The libstagefright issue could potentially be triggered by a malicious MP4 format video file, allowing for arbitrary code execution.
