Detailsinfo

A vulnerability, which was classified as critical, was found in Dialog Semiconductor SDK up to 1.0.14.1081. Affected is some unknown functionality of the component Bluetooth Low Energy. The manipulation as part of a Crafted Packet leads to a buffer overflow vulnerability. CWE is classifying the issue as CWE-120. The product copies an input buffer to an output buffer without verifying that the size of the input buffer is less than the size of the output buffer, leading to a buffer overflow. This is going to have an impact on confidentiality, integrity, and availability. CVE summarizes:

The Bluetooth Low Energy implementation on Dialog Semiconductor SDK through 1.0.14.1081 for DA1468x devices responds to link layer packets with a payload length larger than expected, allowing attackers in radio range to cause a buffer overflow via a crafted packet. This affects, for example, August Smart Lock.

The weakness was shared 02/10/2020. This vulnerability is traded as CVE-2019-17518 since 10/12/2019. The attack can only be initiated within the local network. The exploitation doesn't require any form of authentication. There are neither technical details nor an exploit publicly available.

There is no information about possible countermeasures known. It may be suggested to replace the affected object with an alternative product.
