NOTE: within Adobe Reader, the scope of this issue is limited because the program is deleted and the associated service is not automatically launched after a successful installation and reboot.","cvss_v4":null,"cvss_v3":null,"cwes":["CWE-264"],"references":["http://blogs.adobe.com/psirt/2009/07/local_privilege_escalation_in.html","http://retrogod.altervista.org/9sg_adobe_local.html","http://secunia.com/advisories/35930","http://secunia.com/advisories/36331","http://securitytracker.com/id?1023007"],"products":["adobe:acrobat_reader","corel:getplus_download_manager","nos_microsystems:getplus_download_manager"],"source":"nvd","synced_at":"2026-10-19T19:54:07.895733559+00:00"},"epss":{"cve":"CVE-2009-2564","score":0.05596,"percentile":0.92902,"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).
