In affected versions it is possible to cause a buffer overflow when copying an IPv6 address prefix in the RPL-Classic implementation in Contiki-NG. In order to trigger the vulnerability, the Contiki-NG system must have joined an RPL DODAG. After that, an attacker can send a DAO packet with a Target option that contains a prefix length larger than 128 bits. The problem was fixed after the release of Contiki-NG 4.7. Users unable to upgrade may apply the patch in Contiki-NG PR #1615.\n\n\ud83d\udcd6 Read\n\nvia \"National Vulnerability Database\".", "creation_timestamp": "2022-08-05T00:19:59.000000Z"} {"uuid": "dd43b676-787d-46c3-bdd5-bcd7a3432c2b", "vulnerability_lookup_origin": "1a89b78e-f703-45f3-bb86-59eb712668bd", "author": "9f56dd64-161d-43a6-b9c3-555944290a09", "vulnerability": "CVE-2021-32771", "type": "seen", "source": "https://t.me/cibsecurity/47595", "content": "\u203c CVE-2021-32771 \u203c\n\nContiki-NG is an open-source, cross-platform operating system for IoT devices.
