NOTE: the vendor advisory claims that only a DoS is possible, but the original researcher is reliable.","cvss_v4":null,"cvss_v3":null,"cwes":["CWE-119"],"references":["http://secunia.com/advisories/20497","http://secunia.com/advisories/20658","http://secunia.com/advisories/20899","http://secunia.com/advisories/21222","http://securitytracker.com/id?1016236"],"products":["digium:asterisk"],"source":"nvd","synced_at":"2026-10-19T19:42:44.451428143+00:00"},"epss":{"cve":"CVE-2006-2898","score":0.04293,"percentile":0.91128,"date":"2026-10-31"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
