NOTE: this vulnerability exists because of a CVE-2009-4030 regression, which was not omitted in other packages and versions such as MySQL 5.0.95 in Red Hat Enterprise Linux 6.","published":"2012-10-09T23:55:05.000Z","lastModified":"2026-06-16T23:45:08.000Z","status":"Modified","sourceIdentifier":"secalert@redhat.com","cvss":{"version":"2.0","score":2.1,"severity":"LOW","vector":"AV:L/AC:L/Au:N/C:N/I:P/A:N"},"cwe":["CWE-264"],"affected":["oracle/mysql"],"epss":{"score":0.00398,"percentile":0.33776,"date":"2026-10-26","history":[]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"low","text":"Lower severity and a low EPSS score (0.40%).
