Description
A use-after-free in the time-series collection component of MongoDB Server can occur when the server validates a time-series bucket document during a write. The condition can be caused by an authenticated user with privileges to write bucket documents directly, and may result in the server terminating unexpectedly or, under certain conditions, arbitrary code execution in the context of the server process.
