NOTE: after the initial disclosure, this issue was demonstrated by triggering an integer overflow using an inconsistent size for a Unicode \"Sheet Name\" string.","published":"2006-03-30T11:02:00.000Z","lastModified":"2026-06-16T22:23:10.000Z","status":"Modified","sourceIdentifier":"cve@mitre.org","cvss":{"version":"2.0","score":9.3,"severity":"HIGH","vector":"AV:N/AC:M/Au:N/C:C/I:C/A:C"},"cwe":["CWE-94"],"affected":["microsoft/office"],"epss":{"score":0.28632,"percentile":0.98124,"date":"2026-10-26","history":[]},"kev":{"listed":false},"exploits":{"count":1,"verified":true,"firstPublished":"2006-03-27","source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[{"edbId":1615,"kind":"exploit","title":"Microsoft Office Products - Array Index Bounds Error (PoC)","url":"https://www.exploit-db.com/exploits/1615","sourceUrl":"https://gitlab.com/exploit-database/exploitdb/-/blob/main/exploits/windows/dos/1615.txt","file":"exploits/windows/dos/1615.txt","published":"2006-03-27","added":"2006-03-26","updated":"2017-08-17","author":"posidron","type":"dos","platform":"windows","port":null,"verified":true,"codes":["OSVDB-27150","CVE-2006-1540","OSVDB-24595"],"tags":null,"aliases":"excel_03262006.rar","applicationUrl":null,"screenshotUrl":null,"referenceUrl":null}]},"verdict":{"level":"urgent","text":"EPSS puts the probability of exploitation in the next 30 days at 28.6%, higher than 98% of all known CVEs.
