Contiki-NG up to 4.1 AQL lvm.c lvm_set_type memory corruption

CVSS Meta Temp Score
CVSS is a standardized scoring system to determine possibilities of attacks. The Temp Score considers temporal factors like disclosure, exploit and countermeasures. The unique Meta Score calculates the average score of different sources to provide a normalized scoring system.
Current Exploit Price (≈)
Our analysts are monitoring exploit markets and are in contact with vulnerability brokers. The range indicates the observed or calculated exploit price to be seen on exploit markets. A good indicator to understand the monetary effort required for and the popularity of an attack.
CTI Interest Score
Our Cyber Threat Intelligence team is monitoring different web sites, mailing lists, exploit markets and social media networks. The CTI Interest Score identifies the interest of attackers and the security community for this specific vulnerability in real-time. A high score indicates an elevated risk to be targeted for this vulnerability.

A vulnerability was found in Contiki-NG up to 4.1. It has been classified as critical. This affects the function lvm_set_type of the file os/storage/antelope/lvm.c of the component AQL Handler. The manipulation with an unknown input leads to a memory corruption vulnerability. CWE is classifying the issue as CWE-119. The software performs operations on a memory buffer, but it can read from or write to a memory location that is outside of the intended boundary of the buffer. This is going to have an impact on confidentiality, integrity, and availability. The summary by CVE is:

An issue was discovered in Contiki-NG through 4.1. There is a buffer overflow in lvm_set_type in os/storage/antelope/lvm.c while parsing AQL (lvm_set_op, lvm_set_relation, lvm_set_operand).

The bug was discovered 07/09/2018. The weakness was disclosed 09/07/2018 (Website). It is possible to read the advisory at This vulnerability is uniquely identified as CVE-2018-16664 since 09/07/2018. Attacking locally is a requirement. No form of authentication is needed for exploitation. Technical details of the vulnerability are known, but there is no available exploit.

The vulnerability was handled as a non-public zero-day exploit for at least 60 days. During that time the estimated underground price was around $0-$5k.

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