The maximal size of the prefix is CCNL_MAX_PREFIX_SIZE; the buffer has the size CCNL_MAX_PREFIX_SIZE. However, when NFN is enabled, additional characters are written to the buffer (e.g., the \"NFN\" and \"R2C\" tags). Therefore, sending an NFN-R2C packet with a prefix of size CCNL_MAX_PREFIX_SIZE can cause an overflow of buf inside ccnl_prefix_to_str_detailed.", "severity": [ { "type": "CVSS_V3", "score": "CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H" } ], "affected": [], "references": [ { "type": "ADVISORY", "url": "https://nvd.nist.gov/vuln/detail/CVE-2018-6948" }, { "type": "WEB", "url": "https://github.com/cn-uofbasel/ccn-lite/issues/193" } ], "database_specific": { "cwe_ids": [ "CWE-119" ], "severity": "CRITICAL", "github_reviewed": false, "github_reviewed_at": null, "nvd_published_at": "2018-02-13T17:29:00Z" } }
