CVE-2021-22547

In IoT Devices SDK, there is an implementation of calloc that doesn't have a length check. An attacker could pass in memory objects larger than the buffer and wrap around to have a smaller buffer than required, allowing the attacker access to the other parts of the heap. We recommend upgrading th...
