NOTE: the original Bugtraq post mentioned that code execution was possible, but followup analysis has shown that it is only a null dereference.","cvss_v4":null,"cvss_v3":null,"cwes":[],"references":["http://lists.grok.org.uk/pipermail/full-disclosure/2006-October/050416.html","http://www.gotfault.net/research/advisory/gadv-firefox.txt","http://www.securityfocus.com/archive/1/450155/100/0/threaded","http://www.securityfocus.com/archive/1/450167/100/0/threaded","http://www.securityfocus.com/archive/1/450168/100/0/threaded"],"products":["mozilla:firefox","mozilla:seamonkey"],"source":"nvd","synced_at":"2026-10-19T19:43:14.363260067+00:00"},"epss":{"cve":"CVE-2006-5633","score":0.07472,"percentile":0.9447,"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).
