In versions 4.8 and prior, an out-of-bounds write can occur in the BLE L2CAP module of the Contiki-NG operating system.  The network stack of Contiki-NG uses a global buffer (packetbuf) for processing of packets, with the size of PACKETBUF_SIZE. In particular, when using the BLE L2CAP module with the default configuration, the PACKETBUF_SIZE value becomes larger then the actual size of the packetbuf.  When large packets are processed by the L2CAP module, a buffer overflow can therefore occur when copying the packet data to the packetbuf. The vulnerability has been patched in the \"develop\" branch of Contiki-NG, and will be included in release 4.9. The problem can be worked around by applying the patch manually."}],"metrics":{"cvssMetricV31":[{"source":"security-advisories@github.com","type":"Secondary","cvssData":{"version":"3.1","vectorString":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H","baseScore":8.1,"baseSeverity":"HIGH","attackVector":"NETWORK","attackComplexity":"HIGH","privilegesRequired":"NONE","userInteraction":"NONE","scope":"UNCHANGED","confidentialityImpact":"HIGH","integrityImpact":"HIGH","availabilityImpact":"HIGH"},"exploitabilityScore":2.2,"impactScore":5.9},{"source":"nvd@nist.gov","type":"Primary","cvssData":{"version":"3.1","vectorString":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","baseScore":9.8,"baseSeverity":"CRITICAL","attackVector":"NETWORK","attackComplexity":"LOW","privilegesRequired":"NONE","userInteraction":"NONE","scope":"UNCHANGED","confidentialityImpact":"HIGH","integrityImpact":"HIGH","availabilityImpact":"HIGH"},"exploitabilityScore":3.9,"impactScore":5.9}]},"weaknesses":[{"source":"security-advisories@github.com","type":"Secondary","description":[{"lang":"en","value":"CWE-120"}]},{"source":"nvd@nist.gov","type":"Primary","description":[{"lang":"en","value":"CWE-787"}]}],"configurations":[{"nodes":[{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":true,"criteria":"cpe:2.3:o:contiki-ng:contiki-ng:*:*:*:*:*:*:*:*","versionEndIncluding":"4.8","matchCriteriaId":"729B4607-C6BD-42DE-91BF-918A57D29A77"}]}]}],"references":[{"url":"https://github.com/contiki-ng/contiki-ng/pull/2398","source":"security-advisories@github.com","tags":["Issue Tracking","Patch"]},{"url":"https://github.com/contiki-ng/contiki-ng/security/advisories/GHSA-m737-4vx6-pfqp","source":"security-advisories@github.com","tags":["Patch","Vendor Advisory"]},{"url":"https://github.com/contiki-ng/contiki-ng/pull/2398","source":"af854a3a-2127-422b-91ae-364da2661108","tags":["Issue Tracking","Patch"]},{"url":"https://github.com/contiki-ng/contiki-ng/security/advisories/GHSA-m737-4vx6-pfqp","source":"af854a3a-2127-422b-91ae-364da2661108","tags":["Patch","Vendor Advisory"]}]}}]}
