The 6LoWPAN implementation in Contiki-NG may cast a UDP header structure at a certain offset in a packet buffer. The code does not check whether the packet buffer is large enough to fit a full UDP header structure from the offset where the casting is made. Hence, it is possible to cause an out-of-bounds read beyond the packet buffer. The problem affects anyone running devices with Contiki-NG versions previous to 4.8, and which may receive 6LoWPAN packets from external parties. The problem has been patched in Contiki-NG version 4.8.","state":"PUBLIC","assigner":"security-advisories@github.com","published_at":"2022-09-01 12:15:00","updated_at":"2022-09-07 17:09:00"},"problem_types":["CWE-125"],"metrics":[],"references":[{"url":"https://github.com/contiki-ng/contiki-ng/pull/1648","name":"https://github.com/contiki-ng/contiki-ng/pull/1648","refsource":"MISC","tags":[],"title":"uipbuf: Do not assume that there is enough space for a following extension header by nvt · Pull Request #1648 · contiki-ng/contiki-ng · GitHub","mime":"text/html","httpstatus":"200","archivestatus":"404"},{"url":"https://github.com/contiki-ng/contiki-ng/security/advisories/GHSA-vwr8-6mqv-x7f5","name":"https://github.com/contiki-ng/contiki-ng/security/advisories/GHSA-vwr8-6mqv-x7f5","refsource":"CONFIRM","tags":[],"title":"Out-of-bounds read when decompressing UDP header · Advisory · contiki-ng/contiki-ng · GitHub","mime":"text/html","httpstatus":"200","archivestatus":"404"},{"url":"https://www.cve.org/CVERecord?id=CVE-2022-36052","name":"CVE Program record","refsource":"CVE.ORG","tags":["canonical"]},{"url":"https://nvd.nist.gov/vuln/detail/CVE-2022-36052","name":"NVD vulnerability detail","refsource":"NVD","tags":["canonical","analysis"]}],"affected":[],"timeline":[],"solutions":[],"workarounds":[],"exploits":[],"credits":[],"nvd_cpes":[{"cve_year":"2022","cve_id":"36052","vulnerable":"1","versionEndIncluding":"","cpe1":"cpe","cpe2":"2.3","cpe3":"o","cpe4":"contiki-ng","cpe5":"contiki-ng","cpe6":"*","cpe7":"*","cpe8":"*","cpe9":"*","cpe10":"*","cpe11":"*","cpe12":"*","cpe13":"*"}],"vendor_comments":[],"enrichments":{"kev":null,"epss":null,"legacy_qids":[]},"source_records":{"cve_program":{"CVE_data_meta":{"ASSIGNER":"security-advisories@github.com","ID":"CVE-2022-36052","STATE":"PUBLIC","TITLE":"Out-of-bounds read when decompressing UDP header"},"affects":{"vendor":{"vendor_data":[{"product":{"product_data":[{"product_name":"contiki-ng","version":{"version_data":[{"version_value":"< 4.8"}]}}]},"vendor_name":"contiki-ng"}]}},"data_format":"MITRE","data_type":"CVE","data_version":"4.0","description":{"description_data":[{"lang":"eng","value":"Contiki-NG is an open-source, cross-platform operating system for Next-Generation IoT devices.
