CyberRota Analysis
AI-GeneratedThe Tornado web framework's native extension, tornado.speedups, is vulnerable due to improper validation of the mask argument in the websocket_mask function, potentially allowing buffer over-read. This can lead to unauthorized memory access, which may compromise application integrity and security. Developers and organizations using Tornado versions prior to 6.5.6 should prioritize upgrading to mitigate this risk.

Original NVD Description
Tornado is a Python web framework and asynchronous networking library. Prior to 6.5.6, the optional native extension tornado.speedups implemented websocket_mask without validating that the mask argument is exactly four bytes, allowing the C function to read up to three bytes beyond the provided buffer when reached through Tornado XSRF token decoding with the native extension active. This issue is fixed in version 6.5.6.
