Vulnerability from variot
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. Contiki-NG Exists in an out-of-bounds read vulnerability.Information is obtained and service operation is interrupted (DoS) It may be in a state.
Contiki-NG 4.8 and earlier versions have a buffer error vulnerability, which is caused by an out-of-bounds read problem when processing ICMP DAO input
