NOTE: this issue has been labeled as an integer overflow, but it is more like an integer signedness error.","published":"2006-11-21T23:07:00.000Z","lastModified":"2026-06-16T22:32:17.000Z","status":"Modified","sourceIdentifier":"cve@mitre.org","cvss":{"version":"2.0","score":2.1,"severity":"LOW","vector":"AV:L/AC:L/Au:N/C:P/I:N/A:N"},"cwe":[],"affected":["dragonflybsd/dragonflybsd","freebsd/freebsd","midnightbsd/midnightbsd","netbsd/netbsd","trustedbsd/trustedbsd"],"epss":{"score":0.00421,"percentile":0.3619,"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 (0.42%).
