CVE-2019-13120 (GCVE-0-2019-13120)

Vulnerability from cvelistv5 – Published: 2019-10-07 21:57 – Updated: 2024-08-04 23:41

Summary

Amazon FreeRTOS up to and including v1.4.8 lacks length checking in prvProcessReceivedPublish, resulting in untargetable leakage of arbitrary memory contents on a device to an attacker. If an attacker has the authorization to send a malformed MQTT publish packet to an Amazon IoT Thing, which interacts with an associated vulnerable MQTT message in the application, specific circumstances could trigger this vulnerability.

Severity

No CVSS data available.
