CVE-2021-22547 (GCVE-0-2021-22547)

Vulnerability from cvelistv5 – Published: 2021-05-04 13:05 – Updated: 2024-08-03 18:44

Title

Buffer overrun in Google Cloud IoT Device SDK for Embedded C

Summary

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 the Google Cloud IoT Device SDK for Embedded C used to 1.0.3 or greater.

Severity

6.3 (Medium)
