A vulnerability was found in Contiki-NG up to 4.8. It has been declared as critical. This vulnerability affects the function dao_input_storing
of the component ICMP DAO Packet Handler. The manipulation with an unknown input leads to a out-of-bounds vulnerability. The CWE definition for the vulnerability is CWE-125. The product reads data past the end, or before the beginning, of the intended buffer. As an impact it is known to affect confidentiality, integrity, and availability. CVE summarizes:
Contiki-NG is an operating system for internet of things devices. In version 4.8 and prior, when processing ICMP DAO packets in the `dao_input_storing` function, the Contiki-NG OS does not verify that the packet buffer is big enough to contain the bytes it needs before accessing them. Up to 16 bytes can be read out of bounds in the `dao_input_storing` function. An attacker can truncate an ICMP packet so that it does not contain enough data, leading to an out-of-bounds read on these lines. The problem has been patched in the "develop" branch of Contiki-NG, and is expected to be included in release 4.9. As a workaround, one can apply the changes in Contiki-NG pull request #2435 to patch the system.
