Overview

telemetry is a mechanism used to capture metrics in an application, to later store the data locally or upload it to a server for statistical analysis.

Affected versions of this package are vulnerable to Out-of-Bounds. misc::vec_with_size creates a vector of the provided size and immediately calls vec.set_len(size) on it, initially filling it with uninitialized memory. It then inserts elements using vec[i] = value.clone(). If the value.clone() call panics, uninitialized items in the vector will be dropped leading to undefined behavior.
